Dihybrid test cross

Vedclass · Answer

(D) dihybrid test cross involves crossing an individual heterozygous for two traits (e.g.,$AaBb$) with a homozygous recessive individual (e.g.,$aabb$).According to Mendel's law of independent assortment,the gametes produced by the $AaBb$ individual are $AB$,$Ab$,$aB$,and $ab$ in equal proportions.The homozygous recessive individual produces only $ab$ gametes.Therefore,the resulting offspring genotypes are $AaBb$,$Aabb$,$aaBb$,and $aabb$ in a ratio of $1:1:1:1$.

The ratio $1:1:1:1$ is observed in:
