Vedclass · Answer

(B) Incomplete dominance is a phenomenon where the dominant allele does not completely mask the recessive allele,resulting in an intermediate phenotype in the heterozygote.For a monohybrid cross involving incomplete dominance (e.g.,flower color in Mirabilis jalapa),the $F_2$ generation shows both phenotypic and genotypic ratios as $1: 2: 1$.- The phenotypic ratio is $1$ (Red) : $2$ (Pink) : $1$ (White) = $1: 2: 1$.- The genotypic ratio is $1$ $(RR)$ : $2$ $(Rr)$ : $1$ $(rr)$ = $1: 2: 1$.Therefore,both $P$ and $Q$ are $1: 2: 1$.

The phenotypic ratio of incomplete dominance is $P$.
The genotypic ratio of incomplete dominance is $Q$.
Choose the correct option for $P$ and $Q$.
$P \quad \quad Q$

Describe incomplete dominance.

In Antirrhinum,two plants with pink flowers were hybridized. The $F_1$ plants produced red,pink,and white flowers in the proportion of $1$ red,$2$ pink,and $1$ white. What could be the genotype of the two plants used for hybridization? Red flower color is determined by $RR$,and white by $rr$ genes.
