Vedclass · Answer

(D) In Antirrhinum (snapdragon),flower color exhibits incomplete dominance.Genotype $RR$ produces red flowers,$rr$ produces white flowers,and the heterozygous genotype $Rr$ produces pink flowers.$A$ test cross involves crossing an individual with a recessive parent. Here,the recessive parent is white-flowered $(rr)$.The cross is: Pink $(Rr)$ $	imes$ White $(rr)$.The gametes produced by $Rr$ are $R$ and $r$,and by $rr$ is $r$.The resulting progenies are:$Rr$ (Pink) and $rr$ (White).Thus,the phenotypic ratio is $1 	ext{ Pink} : 1 	ext{ White}$.

When a pink flowered Antirrhinum plant is test crossed,then the phenotypic ratio in the resulting progenies is
