2 What is the ratio of white to colored dogs? Cross two F1 guinea pigs. Please explain in detail - 8048965 B. The self-cross of the F1 generation can be analyzed with a Punnett square to predict the genotypes of the F2 generation. A monohybrid cross is a cross between two organisms with different variations at one genetic locus of interest. 3. What phenotypes are present in the F1 generation? (17) b) Show the F2 generation results – show ALL genotypes and phenotypes as well as your punnet square. If we mated the F1 female and male flies from the cross obtained in problem 3, what male phenotype in the F2 generation would be evidence that crossing over had occured during gamete formation? You will be given seeds from one generation, the F2 (second generation). Want to see the step-by-step answer? In the resulting F2 generation, 3/4 showed the dominant phenotype, and 1/4 showed the recessive phenotype. The answer is explained below by taking the specific example of pea plant in both monohybrid and dihybrid cross. Your job is to to determine what the genotypes of the parents (P) and the first generation (F1) are based on observations of the F2 generation. Repeat Step 1 for Individual #2. x'Y Parents X x XBY XBxb Key XB Normal vision What is P generation? In a dihybrid 9:3:4 ratio where gene A is the epistatic gene, which of the following genotypes will have the same phenotype? Show all your work and explain the importance of your final answer. In a two-factor cross, Mendel followed _____ different genes as they passes from one generation to the next. The sons were yellow-bodied, red-eyed hemizygous. When these F 1 mink were crossed among themselves they produced 47 brown animals and 15 silverblue animals (F 2 generation). Punnett squares are regularly used by geneticists to predict outcomes of crossings between individuals. Daughters were tan-bodied, red-eyed, heterozygous for both eye and body color. 3. Use the punnet A. In a cross between two plants having the same genotypes (R r Y y), the following genotype combinations of offspring are noticed. Results of the F2 generation from Mendel's monohybrid cross. The homozygous genotype AA is a union of two substitution effects of A, one from each sex. In this case, the YY genotype can only produce gametes with a Y genotype, and the yy genotype can only produce gametes with a y genotype. Homozygous and Heterozygous Genotypes. RRYY, rryy. Textbook Solutions 13985. This can be explained … In other words, F1 has less blue kernels than the F2 generation. ¥ F1 all same, F2: 4 different phenotypes ¥ F2 phenotypic ratio is 9:3:3:1 Ð (same as F2 dihybrids in MendelÕs original crosses). Repeat Step 1 for Individual #2. The F 2 generation would have genotypes of (GG, Gg, and gg) and a genotypic ratio of 1:2:1. Question: MONOHYBRID CROSS List The Phenotypes And Genotypes Of The F, Generation Below Showing The Cross For The F2 Generation E Ears Of Corn. 5. What cross will result in a 1 2 1 genotype ratio in the offspring? Punnett square: lists all possible gamete combinations from a cross and figures out all possible genotypes from a cross. Four days after planting, you will make observations about the phenotype of the young plants. F2 generation genotype depends completely on F1 genotype. A method that works for finding the probability of genotypes is to multiply the probably of a zygote getting each allele. Please let me know if anyone finds errors! Hope this was helpful/relevent! What are their phenotypes? Out of a total of 213 offspring, we expect 160 to be white (3/4 x 213). In a dihybrid cross, F2 generation offsprings show four different phenotypes while the genotypes are _____. c) Give the genotype and respective frequency of the gametes produced by the F1 individual and indicate whether the gametes are parental or recombinant. If you get 400 plants in F2, how many of these will be homozygous recessive for both traits? What genotypes are produced in the F1 gen? Genotypic and Phenotypic Ratios. Thus, F2 generation exhibited four different phenotypes and nine different genotypes. d) You cross an F1 Plant with a double homozygous recessive plant (genotype: hhss) and get 1600 plants in F2 generation. B. The green pea phenotype is said to be recessive, meaning that it is only visible in the homozygous individual when the yellow allele is not present. In F2 generation there is a 25% probability that a blue phenotype will be expressed. For example, when a round seed line was crossed to a wrinkled seed line, the F1 generation was all round, and the F2 generation showed a phenotypic ratio of 3 round : 1 wrinkled. F2 phenotypes and genotypes: (F1 gametes): (W) (w) (W) White WW White Ww (w) White Ww Yellow ww From the above Punnett square, 3/4 of the offspring will be white. (There is a Punnett square in purple font to give an example of how you are to fill in your Punnett Square.) Students then need to determine the number out of 100 that should express each phenotype. Instruct students to form a hypothesis of the parents’ (F1 generation) genotypes that would produce the ear they observed in the ears (F2 generation). A plant homozygous for green fruit is crossed with a … By definition, the F2 generation is the result of a cross between two F1 individuals (from F1 generation). The recessive alleles segregate during gamete formation. Mendel showed that the 3:1 ratio of yellow-pod to green-pod plants could only be obtainable if both parents carried a copy of both the yellow and green alleles, and that the yellow allele had to be dominant over green. 6. However, all the genotypes in the F1 generation contain a dominant allele supressing the recessive allele leaving a 0% chance of having a blue phenotype. As a result, one out of four possible combinations of F2-generation plants will have the homozygous recessive genotype (ss). Here the example is used of stem height in pea plants. The offspring are the filial or F generation; F₁ or the first filial represents the children of the parents while the F₂ represents children of the F1 or grandchildren of the parents. The offspring of the F1 generation was the F2 generation (the "grandchildren" of the P generation). This plays a significant role when studying hereditary diseases and illnesses. The law of independent assortment states that a gamete into which an r allele sorted would be equally likely to contain either a Y allele or a y allele. Put these in a Punnett square. b) Give the genotype of resultant F1 progeny. The self-cross of the F1 generation can be analyzed with a Punnett square to predict the genotypes of the F2 generation. 3. The F2 generation would have 2^3=8 different genotypic gametes. The phenotypic and genotypic ratios of the offsprings are determined and written down. a) Show the genotypes of the parents. A heterozygous plant will show a plant with few hairs. Another three gave wrinkled, yellow seeds, and the remaining one plant gave wrinkled green seeds. F2 generation All F1-hybrid plants have the genotype Ssand all are spherical (dominant characteristic). If a cross is made between the two flowers showthe results of this cross (F1 generation) – include ALL genotypes and phenotypes of the F1 generation and show your punnet square. In F2 generation there is a 25% probability that a blue phenotype will be expressed. They support Mendelian inheritance, as well as the laws of segregation and independent assortment. Do not put these beads back into the beaker. Genotypes determine the phenotype in an organism. Out of a total of 213 offspring, we expect 160 to be white (3/4 x 213). So you’re asking for a genotype and phenotype of a homozygous (two identical alleles for a trait) dominant pea plant (tall) and a homozygous recess... The second filial (F2) generation cross of … Answer. A Punnett square can be used to show the expected offspring from two parental groups with known genotypes. The F2 predictions are the next generation in the fruit flies. Given an inheritance pattern of dominant-recessive, the genotypic and phenotypic ratios can then be determined. Record the genotype in Table 1. Today we understand that virtually all body and behavioral traits are heritable. The heritability often falls in the range 40% to 60%, but can be m... Next, Mendel took the F1 progeny and allowed them to self-fertilize. Determine all the genotypes and phenotypes, and their relative ratios, in the F 1 and F 2 generations. fullscreen. 2) List the genotypes of the F2: Pp,Pp,pp,pp 3) List the phenotypes of the F2: 2 purple: 2 yellow Null Hypothesis number 2 Look at your Punnett square crosses and record information about the F2 generation. Question Papers 231. Given an inheritance pattern of dominant-recessive, the genotypic and phenotypic ratios can then be determined. But, F2 generation is the second filial generation of the offspring, generated through inbreeding of F1 individuals. True. The resulting combination is called the F1 generation. Genotypes of the F2: PP , Pp , pp; Phenotypes of the F2: Purple and Yellow Null Hypothesis number 2 Look at your punnet square crosses and record information about the F2 generation. Given an inheritance pattern of dominant-recessive, the genotypic and phenotypic ratios can then be determined. The self-cross of the F1 generation can be analyzed with a Punnett square to predict the genotypes of the F2 generation. The parent or P generation refers to the individuals being crossed. find out the sum total of phenotypes and genotypes in F2 generation if a character is controlled by 4 pair of polygenes. Based on the results, it was confirmed that a ratio could be formulated according to the phenotype of the F2 generation … The resulting generation is the F2 generation (hybrids of hybrids), and the results awaiting him were another surprise to M endel. This is the question I am having trouble with and confused about parental generation, you cross a homozygous long-leafed plant with a homozygous short-leafed plant. Also question is, what is the genotype ratio of the f1 generation? C. Are there more or fewer blue kernels than in the F1 generation? For any test cross the number of phenotypes is 2^n where n=number of heterozygous loci. For e.g. when a monohybrid say Aa is test crossed... Aa * a... 3. The offspring from the F1 generation comprise the second filial generation (or F2 generation). 3. Short plants have skipped the F1 generation, and show up in the F2 and succeeding generations. Question: With independent assortment, the ratio of genotypes in the F2 generation of a cross between true-breeding strains (AA bb × aa BB) can be described as 1:2:1:2:4:2:1:2:1. By definition, the F2 generation is the result of a cross between two F1 individuals (from F1 generation). All F 1 progeny will be heterozygous for both characters (WwDd) and will have white, disk-shaped fruit .. 4. Ears Of Corn And The Potential Offspring. We can add these together … Because of dominance, the phenotype , or visible trait, ratios were 75 percent smooth and 25 percent wrinkled, which can also be written as 3:1. What are the genotype ratios in F2 generation? In the F2 generation of a Mendelian dihybrid cross, the number of phenotypes and genotypes are (a) ... ; genotypes-8 (d) Phenotypes-4; genotypes-9 Give the genotypes of the F2 progeny: 100% heterozygous; G/g, g/g, G/G. For all the different phenotypes Mendel analyzed, the recessive characteristics reemerged in the F 2 generation! For example, when a round seed line was crossed to a wrinkled seed line, the F1 generation was all round, and the F2 generation showed a phenotypic ratio of 3 round : 1 wrinkled. (b) Use a Chi-squared test on the F2 generation data to analyze your prediction of the parental genotypes. 25 . The parental genotypes … This one is the most famous question of this chapter. This can be best understand by the pic here:- Here both genotypic and phenetypic ratio are sa... Yy x Yy F2 generation: Genotype ratio: 1 YY: 2 Yy: 1 yy Phenotype ratio: 3 yellow: 1 green Example of dihybrid cross (cross between true-breeding lines differing in two traits). In this case, Y codes for seed color, R for seed shape (R codes for round seeds, r codes for wrinkled seeds) P generation YYRR x yyrr F1 generation: Punnett square About 3/4 exhibit the dominant phenotype and 1/4 exhibit the recessive phenotype. Based on phenotypic ratios, the genotype may be refined. c) Give the genotype and respective frequency of the gametes produced by the F1 individual and indicate whether the gametes are parental or recombinant. Determine the genotypic and phenotypic ratios for the F2 generation: Genotypic ratios: 1/4 will be homozygous dominant (WW), 1/2 will be heterozygous (Ww) and 1/4 will be homozygous recessive (ww).This is a 1:2:1 genotypic ratio. Possible Gametes of F1: Parent #1 - P and p ; Parent #2 - p and p; Genotypes of F2: Pp : pp (2 heterozygous and 2 homozygous recessive) Phenotypes of F2: 1 : 1 (2 purple to 2 yellow) Based on the punnett square (F1 x F1): Using the given genotypes, find the F1 and F2 generation of the crossed between black rabbit and chinchilla, the crossed of himalayan and albino. (2-3 answers fir each question)1.Which of the following phenotypic ratios in the F2 generation of a monohybrid cross can indicate the presence of a lethal allele?2. Modern scientists now describe the cross of Mendel’s F1 generation as a monohybrid … Repeat Step 3 four more times (for a total of five subsequent generations). ¥ Difference: Ð in original crosses: 2 independent traits/phenotypes=2 independent genes; ¥ Seed color and seed shape Ð here: multiple phenotypes of 1 trait=2 independent genes ¥ Seed color only. allowing the F1 generation to self-fertilize. What genotypes are found in the F2 gen? In sheep white is due to a dominant gene (W), black to its recessive allele (w). P 4. In other words, F1 has less blue kernels than the F2 generation. Monohybrid crosses: The F2 Generation . What are the genotypes of the F2 generation +1. However, all the genotypes in the F1 generation contain a dominant allele supressing the recessive allele leaving a 0% chance of having a blue phenotype. Three of them exhibited round green seeds. Set up a Punnett square and determine the genotypes and phenotypes for this cross. 0. first u cross the f1 generation then u take two different offspring from f1 generation n cross them n u will get the genotypes of th f2 generation. When Mendel allowed the F 1 plants to self-fertilize, the F 2 generation showed two different phenotypes, indicating that the F 1 plants had different genotypes. In the resulting F2 generation, 3/4 showed the dominant phenotype, and 1/4 showed the recessive phenotype. The resulting generation is the F2 generation (hybrids of hybrids), and the results awaiting him were another surprise to M endel. Set up a Punnett square and determine the genotypes and phenotypes for this cross. Online Tests 73. 12. 12 3 1 How many genes? Let take pure breeding plants as parents, that is, red flower bearing plant and white flower bearing plant with ‘RR’ and ‘rr’ as their genotypes re... The zygote genotypes are the target of all this preparation. In other words, F1 has less blue kernels than the F2 generation. Determine the genotypic and phenotypic ratios for the F 1 generation:. Predict the genotypes and phenotypes of the F2 generation when completing the Punnett square. This Punnett square shows the expected phenotypes of the offspring, which will have a 3:1 black-to-red ratio. INCOMPLETE DOMINANCE : If the dominant allel is unable to mark the expression of its recessive allel, the hybrid will show a phenotype intermediate... In the F2 generation, only 1 of the 4 boxes produced green peas. Important Solutions 3696. b. Example: Consider two genes A and B each with two alleles - A1 & A2: B1 & B2. F2 phenotypes and genotypes: (F1 gametes): (W) (w) (W) White WW White Ww (w) White Ww Yellow ww From the above Punnett square, 3/4 of the offspring will be white. See Answer. RrYy. Show all your work and explain the importance of your final answer. 3. F2 generation is developed as a result of cross-breeding of two F1 generation offspring together. The cross between the true-breeding P plants produces F1 heterozygotes that can be self-fertilized. These two genotypes represent the parents (generation P) for the next generation. P generation YY x yy (usually listed female x male) | F1 generation Yy. The F2 generation was the result of repeatedly crossing F1 boars with F1 sows in order to obtain large full-sib families. Additionally, different genes are assorted and inherited independently from on another; the probability of one phenotype does not affect the probability of another. This is the question I am having trouble with and confused about The trait for round (R) peas is dominant over the trait wrinkled (r) peas. Use a Chi-squared test on the F2 generation data to analyze your prediction of the parental genotypes. Record your data in Table 2. Give the four classes of the F2 plants that you will see. O allele is a recessive allele, which means that both alleles of the gene need to be O to express phenotype O. However, A is a co dominant allele w... … He then planted and observed the offspring from this cross. 4. Explanation: Let us take both monohybrid and dihybrid cross. a) Give genotypes of two pure breeding parents. Like in the dihybrid cross, the F1 generation produced in a monohybrid cross are all heterozygous and only the dominant phenotype is observed. However, the phenotypic ratio observed in the F2 generation is 3:1. About 3/4 exhibit the dominant phenotype and 1/4 exhibit the recessive phenotype. answer (click here)-----Question 5. The character(s) being studied in a monohybrid cross are governed by two or multiple variations for a single locus. What is the genotype ratio of the f1 generation? The phenotypic ratio is 9:3:3:1 whereas the genotypic ratio is 1:2:1:2:4:2:1:2:1. Similarly, what is the genotype of the f1 generation? In contrat, the F2 generation may exhibit some parental phenotypes. To what genotype does the "4" in the ratio refer? As in a dihybrid cross, the F1 generation plants produced from a monohybrid cross are heterozygous and only the dominant phenotype is observed. The phenotypic and genotypic ratios of the offsprings are determined and written down. Punnett squares are diagrams designed to predict results of classic breeding experiments. Black (CC) × Chinchilla (Cch Cch) squares below to guide you. Draw A Punnett Square 1. Looking at a Punnett square is the best way for both types incomplete and co-dominance. You figure it out by looking at all the possibilities for a... In this scientific inquiry activity, students germinate F2 generation Wisconsin Fast Plants® seeds and identify the phenotypes and possible genotypes of the F2 generation plants. when AaBb crossed with aabb then , AaBb produces 4 types of gamates i.e AB, Ab, aB and ab etc. And aabb produces only one type of gamate i.e ab. Th... Maharashtra State Board HSC Science (General) 12th Board Exam. The F1 progeny are then crossed to each other to produce the F2 generation. selection criteria for high yieldi g genotypes in early f2 GENERATION OF TWELVE INTER VARIETAL CROSSES OF Brassica rapa S. Parveen', M. H. RashidI and M. S. R. Bhuiyan'' Look at your Punnett square crosses and record information about the F2 generation. e. The recessive alleles segregate during gamete formation. Should the F 1 generation be allowed to self-pollinate, the potential allele combinations will be different in the next generation (F 2 generation). These two genotypes represent the parents (generation P) for the next generation. F2 23 31 22 24 0 (a) Determine the genotypes of the original parents (P generation) and explain your reasoning. The effectiveness of the O2 RFLP marker assay was tested under field conditions using F2 and backcross populations of several hard endosperm opaque-2 lines. What are the genotypic and phenotypic ratios of the f2 generation? Mendel took a plant from the F1 generation, and allowed that plant to self-fertilize. Check out a sample Q&A here. Mendel found that crossing two purebred pea plants which expressed different traits resulted in an F 1 generation where all the pea plants expressed the same trait or phenotype. Phenotypic ratios: 3/4 will have white fruit color and 1/4 will have yellow fruit color.This is a 3:1 phenotypic ratio. For the F2 generation, the law of segregation requires that each gamete receive either an R allele or an r allele along with either a Y allele or a y allele. a) Give genotypes of two pure breeding parents. Draw a Punnett square illustrating this cross, and give the genotypes and phenotypes of the F1 generation. Mendel observed that the F2 generation contained a mixture of green and yellow pods. The probable combination of the genotypes is written within the Punnet square as all combinations are possible as the process of fertilization is random. Give the ratios above Incomplete dominance: A hairy plant allele is dominant over a hairless allele. F2 = 118 white 32 black 10 brown # Find the genotypes of the dogs in each class: What is the ratio? RrYy. As a result, one out of four possible combinations of F2-generation plants will have the homozygous recessive genotype (ss). Complex Punnet Square Probability. Modes of inheritance can also be determined through experiments with true-breeding individuals (i.e. find out the sum total of phenotypes and genotypes in F2 generation if a character is controlled by 4 pair of polygenes. Use a Chi-squared test on the F2 generation data to analyze your prediction of the parental genotypes. A − R r Y Y B − R r y y C − r r Y y D − r r y y The phenotypic features of A, B, C and D are given below in an order in four combinations. All offspring from a cross between a homozygous male with type A blood and a homozygous female with type B blood are going to be heterozygous Type... 3 Using these probabilities, we can predict the phenotypic ratio we should see in the F2 generation. To construct a Punnett square, the genotypes of both parents must be … To carry out such a cross, each parent is chosen to be homozygous or true breeding for a given trait (locus). Here, we overcome these shortcomings by pooling four large F2 designs to produce smaller linkage disequilibrium blocks and by resequencing the founder generation at high coverage and the F1 generation at low coverage for subsequent imputation of the F2 generation to whole genome sequencing marker density. In F2 generation there is a 25% probability that a blue phenotype will be expressed. Determine the F 1 gametes, place them in a Punnett Square and fill in the resulting genotypes: 2 Write the genotypes of the true-breeding plants that Mendel used in his two factor cross. 12:4 = 3:1 This means that white is dominant to colored so let Õs call one gene: W= white w=colored Sample Problem WwDd (white, disk-shaped fruit) X WwDd (white, disk-shaped fruit) 5. Based on our collected data and our % error, our hypothesis was not supported. In a monohybrid cross, the F2 generation is produced by. Since each of the 3 heterozygous loci lead to 3 different genotypes representing 2 different phenotypes, the F2 generation would have 3^3 different genotypes comprising 2^3 different phenotypes. From the crosses, a total number of 2772 animals were chosen (24 F0-generation pigs, 91 F1-generation pigs, 2657 F2-generation pigs) and blood samples were used to extract genomic DNA for genotyping purposes . During meiosis, chromatids are separated such that each gamete receives only one allele. This is an example of incomplete dominance. Looking at the original question, AABbcc x aaBbCc. Because it is a cross of the offspring, it represents the second filial generation, or F2 generation. F2 generation is referred to as a second filial generation of offspring. The resulting F2 genotype ratios were 25 percent SS, 50 percent Ss and 25 percent ss, which can also be written as 1:2:1. The F2 generation will contain many more than 4 individuals, but they will likely show the same ration. Comment; Complaint; Link; Know the Answer? Results of the F2 generation from Mendel's monohybrid cross. What are the phenotype ratios in F2 generation? Look at the punnett square and asses the information about the F2 generation. 6. Upon statistically analyzing the F2 generation, Mendel determined the ratio of tall to short plants was approximately 3:1. A geneticist can provide probabilities for certain genotypes and phenotypes before the breeding takes place. Furthermore, the F1 generation is distinctly different from the parental types. Mendel observed that the F2 generation contained a mixture of green and yellow pods. A monohybrid cross is one that involves only one trait. One-fourth of the F 2 generation would be homozygous dominant (GG), one-half would be heterozygous (Gg), and … This is the genotype of Individual #1. RRYY, rryy. The phenotypic ratio of the resulting F2 generation is 3:1. What Is The Expected Ratio Of … The green pea allele was present in the F1 generation, but the phenotype was hidden by the yellow pea allele. The resulting combination is called the F1 generation. Monohybrid Cross: F2 generation . Have them predict the ratio of phenotypes that this cross would produce. This information is transferred to the Punnett square, and the possible genotypes are extracted. Our group's hypothesis was that if white-eye mutation was sex-linked recessive in the first parent (P) generation, then by the F2 generation the expected phenotype ratio is 1:1:1:1 (x,xw X xwy) and 2:1:1 (x,xw X xwy). Using a Punnett square, show the genotypes and phenotypes of the F2 generation if the F1 plants in question 1 are self-fertilized. We get F2 generation by allowing pollinaton amig plants of F1 generation. Instead of 4 possible genotypes from a monohybrid cross, dihybrid crosses have as many as 16 possible genotypes. Answers (1) Oneal 17 April, 06:30. You may use Punnett squares to enhance your description, but the results from the Punnett squares must be discussed in your answer. Want to see this answer and more? True or false: Crossing pure breed white flowered pea plants with pure breed purple flowered pea plants produced hybrid pea plants with purple flowers. The expected genotype ratio when two heterozygotes are crossed is 1 (homozygous dominant) : 2 (heterozygous) : 1 (homozygous recessive). Gametes of the F1: P , p; Genotypes of the F2: Pp , pp; Phenotypes of the F2: … b) Give the genotype of resultant F1 progeny. The parental genotypes … This is best illustrated by example. What are the genotypes of the F2 generation? All F1-hybrid plants have the genotype Ss and all are spherical (dominant characteristic). What are the genotypes and phenotypes of the F2 generation? Probability of F1 pollen x Probability of F1 ovule = Probability of F2 genotype 1 2 R 1 2 R 1 4 RR 1 2 R 1 2 r 1 4 Rr 1 2 r 1 2 R 1 4 Rr 1 2 r 1 2 r 1 4 rr Note that there are two ways of producing “Rr” in the F2 generation. Expected Phenotypes of F2 Cross - Two Autosomal Traits (Unlinked) The Expected Genotypic and Phenotypic Arrays of two unlinked genes considered jointly are the product of the separate Genotypic and Phenotypic Arrays. Since we know what the genotypes for the F1 generation are, we can now make predictions for the F2 generation. However, all the genotypes in the F1 generation contain a dominant allele supressing the recessive allele leaving a 0% chance of having a blue phenotype. Write down the cross between F 1 progeny:. Determine the genotypes of the F2 generation in this example of X-linked inheritance of color blindness. Gametes R R Rr Rr Round Round Rr Rr Round Round + Gametes d. What percentage of the F2 generation will have round seeds? The vials contain the same flies, but we want to know what the offspring of the F1 generation will be. one trait. In cucumbers, green fruit color (G) is dominant over cream fruit color (g). The probable combination of the genotypes is written within the Punnet square as all combinations are possible as the process of fertilization is random. For all the different phenotypes Mendel analyzed, the recessive characteristics reemerged in the F 2 generation! Please explain in detail - 8048965 This is called a monohybrid cross : "mono" because only one trait varied, and "hybrid" because offspring represented a mixture, or hybridization, of plants, as one parent has one version of the trait while one had the other version. What gametes do F1 generation make? Yellow round pea plants (9) will have 4 types of genotypes: YYRR (1), … The offsprings in F2 generation will be yellow round: yellow wrinkled: green round : green wrinkled in ration of 9:3:3:1. check_circle Expert Answer.
