Vedclass · Answer

(C) The given situation is an example of incomplete dominance,where the phenotype in the $F_1$ generation does not resemble either of the two parents.In $Antirrhinum$ (snapdragon),the cross between a red-flowered plant $(RR)$ and a white-flowered plant $(rr)$ results in pink-flowered plants $(Rr)$ in the $F_1$ generation.When two pink-flowered plants $(Rr)$ are hybridized,the cross is $Rr 	imes Rr$.The resulting offspring genotypes are $1 RR$ (red) : $2 Rr$ (pink) : $1 rr$ (white).Therefore,the genotype of the two plants used for hybridization is $Rr$.

In Antirrhinum,two plants with pink flowers were hybridized. The $F_1$ plants produced red,pink,and white flowers in the proportion of $1$ red,$2$ pink,and $1$ white. What could be the genotype of the two plants used for hybridization? Red flower color is determined by $RR$,and white by $rr$ genes.
