Gray seed color in peas is dominant to white Assume that Men

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. What is the most probable genotype of each parent? 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.) Select one: Gg times Gg; genotypic = 1:2:1, phenotypic = 3:1 gg times Gg; genotypic = 1:2, phenotypic = 3:1 GG times gg; genotypic = 3:1, phenotypic = 1:2:1 GG times Gg; genotypic = 1:2:1, phenotypic = 2:1

Solution

Answer: A. (a)Gg x Gg; (b) genotypic = 1:2:!, phenotypic = 3:1

Explanation:

GG or Gg = Gray

gg = white

Gg (Gray) X Gg (Gray)-----------Parents

Genotypic ratio: GG : Gg :gg = 1 : 2 : 1

Phenotypic ratio: Gray : white = 3:1

	G	g
G	GG (Gray)	Gg (Gray)
g	Gg (Gray)	gg (white)
