Vedclass · Answer

(C) In incomplete dominance,the dominant allele does not completely mask the effect of the recessive allele. In $Antirrhinum$ $majus$ (Snapdragon),when a red-flowered plant $(RR)$ is crossed with a white-flowered plant $(rr)$,the $F_1$ generation produces pink-flowered plants $(Rr)$. When these $F_1$ pink-flowered plants $(Rr)$ are self-pollinated to obtain the $F_2$ generation,the resulting phenotypic ratio is $1$ (Red) : $2$ (Pink) : $1$ (White). Thus,the phenotypic ratio in the $F_2$ generation is $1 : 2 : 1$,which is identical to the genotypic ratio.

In the phenomenon of incomplete dominance observed in $Antirrhinum$ $majus$ (Snapdragon),what is the phenotypic ratio of the progeny in the $F_2$ generation?
