(C) In garden pea plants,red flower color is dominant over white flower color. Let $R$ represent the dominant allele for red flowers and $r$ represent the recessive allele for white flowers.$P$ generation: $RR$ (Red) $	imes$ $rr$ (White)$F_1$ generation: All offspring are $Rr$ (Red).When $F_1$ plants $(Rr)$ are self-pollinated $(Rr 	imes Rr)$:Using a Punnett square:| | $R$ | $r$ ||---|---|---|| $R$ | $RR$ | $Rr$ || $r$ | $Rr$ | $rr$ |Genotypes: $1 RR : 2 Rr : 1 rr$Phenotypes: $3$ Red $(RR, Rr, Rr)$ : $1$ White $(rr)$.Therefore,the phenotypic ratio in the $F_2$ generation is $3:1$.

If in a garden pea plant,a cross is made between red flowered and white flowered plants,what will be the phenotypic ratio in the $F_2$ generation?
