Vedclass · Answer

(D) In a dihybrid cross involving two traits (e.g.,seed shape and seed color),the $F_2$ generation follows the phenotypic ratio of $9:3:3:1$ and a genotypic ratio. For two genes,let the alleles be $Aa$ and $Bb$. $A$ plant that is heterozygous for both traits has the genotype $AaBb$. In the $F_2$ Punnett square of a dihybrid cross,the total number of combinations is $16$. The genotype $AaBb$ appears in $4$ out of the $16$ squares. Therefore,the probability is $4/16$ (or $1/4$).

In Mendel's dihybrid cross,what is the probability of obtaining a plant that is heterozygous for both traits (in $/16$)?
