Incompletely dominant

Vedclass · Answer

(B) In incomplete dominance, the dominant allele does not completely mask the effect of the recessive allele. As a result, the phenotype of the heterozygote $(Rr)$ is an intermediate blend of the two homozygous parents ($RR$ and $rr$). In this specific case, the cross between red $(RR)$ and white $(rr)$ flowers results in pink $(Rr)$ offspring, which is a classic example of incomplete dominance observed in plants like $Mirabilis$ $jalapa$ (Four o'clock plant).

$RR$ (red) is crossed with $rr$ (white). All $Rr$ offspring are pink. This indicates that the gene is .......
