Vedclass · Answer

(C) In incomplete dominance,the dominant allele does not completely mask the recessive allele. In $Antirrhinum$ (snapdragon),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 the following genotypes: $1 RR$ (red) : $2 Rr$ (pink) : $1 rr$ (white). Thus,the phenotypic ratio of red,pink,and white flowers is $1 : 2 : 1$. Since the question asks for the ratio of pink,red,and white flowers respectively,the ratio remains $2 : 1 : 1$ based on the order provided in the question.

In $Antirrhinum$ (snapdragon) plants,what is the phenotypic ratio of pink,red,and white flowers respectively in the $F_2$ generation due to incomplete dominance?
