Genotypic ratio equal to phenotypic ratio

Vedclass · Answer

(A) In incomplete dominance, the dominant allele does not completely mask the effect of the recessive allele. As a result, the heterozygous condition shows an intermediate phenotype. For example, in the snapdragon $(Antirrhinum majus)$, the cross between red $(RR)$ and white $(rr)$ flowers results in pink $(Rr)$ flowers in the $F_1$ generation. When $F_1$ plants $(Rr)$ are self-pollinated, the $F_2$ generation shows a phenotypic ratio of $1:2:1$ (Red:Pink:White) and a genotypic ratio of $1:2:1$ $(RR:Rr:rr)$. Therefore, the genotypic ratio is equal to the phenotypic ratio.

In the case of incomplete dominance, the $F_2$ generation has:
