Vedclass · Answer

(B) In a dihybrid cross, the $F_2$ phenotypic ratio is $9:3:3:1$. Individuals showing one dominant and one recessive character are represented by the two groups of $3$ in the ratio (i.e., $3 + 3 = 6$). These phenotypes correspond to the genotypes $AAbb$ and $aaBB$ (or $Yyrr$ and $yyRr$ in the case of seed color and shape). Therefore, the total proportion of individuals showing one dominant and one recessive trait is $6/16$.

During a dihybrid cross, in the $F_2$ generation, the ratio of individuals showing one dominant and the other recessive character will be . . . . . . of the total population. (in $/16$)
