Gray Seed Color in Peas Is Dominant to White

question 57

Multiple Choice

Gray seed color in peas is dominant to white. Assume that Mendel conducted a series of experiments where plants with gray seeds were crossed among themselves, and the following progeny were produced: 302 gray and 98 white.
(a) What is the most probable genotype of each parent?
(b) Based on your answer in (a) above, what genotypic and phenotypic ratios are expected in these progeny? (Assume the following symbols: G = gray and g = white.)

• A) (a) GG × gg; (b) genotypic = 3:1, phenotypic = 1:2:1
• B) (a) Gg × Gg; (b) genotypic = 1:2:1, phenotypic = 3:1
• C) (a) GG × Gg; (b) genotypic = 1:2:1, phenotypic = 2:1
• D) (a) gg × Gg; (b) genotypic = 1:2, phenotypic = 3:1
• E) (a) Gg × Gg; (b) genotypic = 3:1, phenotypic = 9:3:3:1
