Assuming random mating, and assuming that the plants cannot self-fertilize, if you collect the fertilized seeds from a plant (i.e., a single individual within the parental population of the pea plants), that has white flowers, and plant them, and rear the offspring, what genotypes and phenotypes do you expect to observe, and at what frequencies?

WW = white, RR = Red, WR = Pink

Freq (R) = 0.8

Freq (W) = 0.2

The answer is RW (pink flowers) at freq 0.8 and WW (white flowers) at 0.2.

Why is the frequency of the RW 0.8 and WW 0.2 for the generation that I will plant. I don’t understand that logic of it. It’s hat simply based on the overall frequency of the alleles and the offspring will reflect that?
