In peas, gray seed color is dominant to white. For the purposes of this question, assume that Mendel crossed plants with gray seeds with each other and the following progeny were produced: 320 gray and 80 white. a) What is the most probable genotype of each parent? a) What genotypic and phenotypic ratios are expected in the progeny of such a cross?
Answer
(a) assuming the following symbols: G = gray and g = white, Gg × Gg (b) genotypic = 1:2:1, phenotypic = 3:1
