Vedclass · Answer

(D) In incomplete dominance,the dominant allele does not completely mask the effect of the recessive allele. As a result,the $F_{1}$ generation exhibits a phenotype that is an intermediate blend of the two parental traits. For example,in $Antirrhinum$ $majus$ (snapdragon),a cross between red $(RR)$ and white $(rr)$ flowers results in pink $(Rr)$ flowers in the $F_{1}$ generation. In the $F_{2}$ generation,the genotypic ratio is $1:2:1$ $(RR:Rr:rr)$ and the phenotypic ratio is also $1:2:1$ (Red:Pink:White). Therefore,the phenotypic and genotypic ratios are identical in incomplete dominance,which contradicts option $B$. However,looking at the options provided,option $D$ is the most accurate description because the $F_{1}$ phenotype is an intermediate expression resulting from the influence of both alleles.
