In corn, seedling color is determined by genes at two loci (C/c and D/d). Suppose that you cross a pure-breeding green seedling with a pure-breeding yellow seedling and obtain only green seedlings in the F1 generation. You then cross two of the F1 seedlings and obtain the following progeny for the F2 generation: 138 green seedlings, 33 virescent-white seedlings, and 10 yellow seedlings. What form of epistasis would explain these data?

Figure 8.10 In pea plants, purple flowers (P) are dominant to white (p), and yellow peas (Y) are dominant to green (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares would you need to complete a Punnett square analysis of this cross?
If a pure-breeding purple-flowered pea plant is crossed with a pure-breeding white-flowered pea plant, all the offspring have purple flowers. Suppose two F1 plants are crossed, and 1200 offspring are obtained. How many white-flowered plants will you expect?
In the tomato, yellow flowers (Y) is dominant to white flowers (y). A true-breeding yellow flowered strain is crossed with a true-breeding white flowered strain.A. If the F1 generation is self crossed, what will be the genotypes and phenotypes of the progeny and in what portions are they expected? B. If an F1 plant were crossed with a plant from true-breeding white flowered strain, what will be the genotypes and phenotypes of the progeny and in what portions are they expected?
You self-fertilize an F1 plant to produce the F2 generation. Based on Mendelian principles of inheritance, what fraction of the F2 generation do you expect to be short with round, green seeds? HINT: Solving this problem will require a very large Punnett square (8 x 8), but you can easily solve it using the Multiplication Rule
In tomatoes, tall (D) is dominant over dwarf (d) and smooth fruit (P) is dominant over pubescent fruit (p), which is covered with fine hairs. A farmer has two tall and smooth tomato plants, which we will call plant A and plant B. The farmer crosses plants A and B with the same dwarf and pubescent plant and obtains the following numbers of progeny: Q. Explain why different proportions of progeny are produced when plant A and plant B are crossed with the same dwarf pubescent plant.
What would be the size and genotype of the F1 from a cross between a true-breeding 11 cm plant and a true-breeding 47 cm plant?
In snapdragons, red flower color (R) is incompletely dominant over white flower color (r), so that the heterozygote has pink flowers. A red snapdragon is crossed with a white snapdragon, and the F1 are intercrossed to produce F2. What is the genotype and phenotypes of the F1 and F2, along with their expected proportions? If the F1 are backcrossed to the white parent, what will be the expected genotype and phenotype of the offspring? If the F1 are backcrossed to the red parent and the resulting progeny are intercrossed, what is the expected proportions of genotypes and phenotypes in the progeny?
In pea plants, purple flowers (P) are dominant to white flowers (p) and yellow peas (Y) are dominant to green peas (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares do you need to do a Punnett square analysis of this cross?
The crossing of two orange-flowering plants results in ~2/3 orange-flower progeny and ~1/3 white-flower progeny. The crossing of two orange-flowering F1 plants generates the same progeny ratios as observed for the parental cross, while the crossing of white-flowering F1 plants only produces white-flowering progeny. What is a likely explanation for these results?
You have a pure breeding plant with red flowers, yellow seeds and red-veined leaves. You cross this with another pure breeding plant that has white flowers, pink seeds and yellow leaf veins. All of the offspring (F1) have white flowers, yellow seeds and orange leaf veins. Assuming all three loci are independently assorting, use this information to answer the following question: If two F1 offspring are crossed with each other and 1000 F2 are obtained, approximately how many offspring should have orange leaf veins? a. 1000 b. 750 c. 500 d. 250 e. Cannot be determined with this information
In pumpkins, the discoid fruit shape (D) is dominant to the spherical shape (d) and the white color of the shell (B) is dominant to green (b). Suppose the following cross is made: DDBBxddbb...to. If in an F2 320 pumpkins are obtained, how many of them are expected to be...Yo. white-discordant.ii. white-spherical.iii. green-discoidiv. green-spherical.b. If you cross a BbDd plant with a double recessive one and you get 100 pumpkinsWhat proportions do you expect to obtain from each of the following phenotypes?1. white-discordant.2. white-spherical3. green-discoids4. green-sphericalc. Based on your answer, are the genes involved in fruit color and shape linked or independent? Because?
A cross between two red flower plants produces 2/3 progeny that are red and1/3 progeny that are yellow. What is the genotype of the red flower? Explain these unexpected ratios.
