Vedclass · Answer

(B) Mirabilis jalapa exhibits incomplete dominance,where the heterozygous condition $(Rr)$ results in a pink phenotype instead of red.When a pink-flowered plant $(Rr)$ is crossed with a white-flowered plant $(rr)$,the gametes produced by the pink plant are $R$ and $r$,while the white plant produces only $r$ gametes.The resulting offspring genotypes are $Rr$ (pink) and $rr$ (white) in a $1: 1$ ratio.Therefore,the expected phenotypic ratio is $1$ pink : $1$ white.

In Mirabilis,a hybrid for red $(RR)$ and white $(rr)$ flower produces pink $(Rr)$ flower. $A$ plant with pink flower is crossed with a white flower,the expected phenotypic ratio is
