Question

Snapdragons are incompletely dominant for color. They have phenotypes; red, white, or pink. Red flowers are homozygous dominant, white flowers are homozygous recessive, and pink flowers are heterozygous. What are the genotype and phenotype ratios for a pink female and a pink male?

Answer 1

The genotype ratio for a pink female and a pink male snapdragon is 1 CRCW:1 CRCW. The phenotype ratio is 1:1 for pink flowers.

Step-by-step explanation:

In snapdragons, the phenotype of pink flowers is the result of incomplete dominance. A pink female snapdragon carries the genotype CRCW, while a pink male snapdragon also carries the genotype CRCW. This means that both male and female pink snapdragons are heterozygous for flower color.

The genotype ratio for a pink female and a pink male snapdragon is 1 CRCW:1 CRCW. The phenotype ratio, which represents the observed flower colors, is 1:1 for pink flowers.
