Vedclass · Answer

(A) dihybrid test cross involves crossing an $F_1$ dihybrid individual (genotype $AaBb$) with a homozygous recessive individual (genotype $aabb$).Since the $F_1$ individual produces four types of gametes $(AB, Ab, aB, ab)$ and the recessive parent produces only one type of gamete $(ab)$,the resulting offspring will have four different phenotypes in equal proportions.The resulting phenotypic ratio is $1:1:1:1$.
