Snapdragons have incomplete dominance of the red and white alleles. What will be the phenotypes and ratios of the F₂ generation?

Question

Quizplus · Accepted Answer

Incomplete dominance means that blending of traits occurs in the heterozygous condition. In the case of snapdragons, the F₂ plants will have one red allele and one white allele, resulting in the phenotype of pink flowers. This means that the offspring will have a ratio of 25% white (RR genotype), 50% pink (RW genotype), and 25% red (WW genotype). Therefore, the best choice is option B.
