(D) In a dihybrid cross between $AABB$ and $aabb$,the $F_1$ generation produces all $AaBb$ individuals.When $F_1$ individuals $(AaBb)$ are self-crossed,the $F_2$ generation follows the Mendelian dihybrid ratio of $9:3:3:1$.In the Punnett square for a dihybrid cross,the genotype $AaBb$ appears in $4$ out of $16$ squares.Therefore,the ratio of $AaBb$ in the $F_2$ generation is $4/16$ (or $1/4$).

When $AABB$ and $aabb$ are crossed,in $F_2$ generation the ratio of $AaBb$ will be (in $/16$)
