Incomplete dominance

Vedclass · Answer

(B) The given experiment shows a cross between red-flowered $(RR)$ and white-flowered $(rr)$ plants of $Antirrhinum$ $sp.$ (Snapdragon).In the $F_1$ generation,all plants are pink $(Rr)$,which is an intermediate phenotype between red and white.In the $F_2$ generation,the phenotypic ratio is $1:2:1$ (Red:Pink:White),which is identical to the genotypic ratio.This phenomenon,where the dominant allele does not completely mask the recessive allele,resulting in an intermediate phenotype,is known as Incomplete dominance.

Incomplete dominance is found in

$A$ plant with red flowers was crossed with another plant with yellow flowers. If $F_1$ showed all flowers orange in colour,explain the inheritance.

$A$ : In snapdragon, $F_{1}$ plants do not have red or white flowers.
$R$ : It is intermediate inheritance with neither of the two alleles of a gene being dominant over each other.

In a Mendelian cross,the $F_2$ generation shows that both the genotypic ratio and the phenotypic ratio are the same,i.e.,$1:2:1$. This indicates:

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