(A) In snapdragon ($Antirrhinum$ $sp.$),flower color inheritance exhibits incomplete dominance.When a red-flowered plant $(RR)$ is crossed with a white-flowered plant $(rr)$,the $F_1$ generation produces pink-flowered plants $(Rr)$.When $F_1$ plants $(Rr)$ are self-pollinated,the $F_2$ generation results in the following genotypes: $1$ $RR$ (red) : $2$ $Rr$ (pink) : $1$ $rr$ (white).Thus,the phenotypic ratio in the $F_2$ generation is $1:2:1$.

In a cross between red and white flowered snapdragon ($Antirrhinum$ $sp.$),the $F_2$ generation has red,pink,and white flowered plants in the ratio of:
