Vedclass · Answer

(D) The genotype of the plant is $AABb$. When this plant undergoes selfing,the cross is $AABb 	imes AABb$. We can analyze the inheritance of each gene pair independently: $1$. For the $AA$ gene pair: $AA 	imes AA$ results in all $AA$ offspring (homozygous dominant). $2$. For the $Bb$ gene pair: $Bb 	imes Bb$ results in a phenotypic ratio of $3:1$ ($3$ dominant : $1$ recessive). Combining these results: Since the $AA$ trait is uniform,the phenotypic ratio of the offspring will be determined solely by the $Bb$ trait. Therefore,the phenotypic ratio is $3:1$. As $3:1$ is not among the given options,the correct answer is $D$ (None of these).

What will be the phenotypic ratio obtained from the selfing of a plant with the genotype $AABb$?
