Question

In snapdragons, flower color is determined by a gene that follows an incomplete dominance pattern. In this species, the red allele (R) produces red flowers, and the white (W) allele produces white flowers. The heterozygous individual produces a blended phenotype of pink flowers.

If a red snapdragon is cross pollinated with a pink snapdragon, calculate the probability that the offspring will have white flowers.

Answer 1

Genotypes: red = RR, pink = RW. Cross RR × RW → offspring: 50% RR (red), 50% RW (pink), 0% WW (white).

So the probability of white flowers = 0%.
