Vedclass · Answer

(D) In incomplete dominance, the dominant allele does not completely mask the recessive allele. As a result, the heterozygous phenotype is an intermediate between the two homozygous phenotypes. For example, in $Mirabilis jalapa$ (four-o'clock plant), a cross between red $(RR)$ and white $(rr)$ flowers results in pink $(Rr)$ flowers in the $F_1$ generation. When $F_1$ hybrids $(Rr)$ are self-pollinated, the $F_2$ generation shows a phenotypic ratio of $1$ (red) : $2$ (pink) : $1$ (white). The genotypic ratio is also $1$ $(RR)$ : $2$ $(Rr)$ : $1$ $(rr)$. Therefore, both the phenotypic and genotypic ratios are $1:2:1$.
