(A) In a dihybrid cross involving two traits (e.g.,seed shape and seed color),the $F_2$ generation follows a phenotypic ratio of $9:3:3:1$. However,the question asks for the proportion of dominant homozygous plants. Let the traits be represented by alleles $R$ (round) and $Y$ (yellow),which are dominant over $r$ (wrinkled) and $y$ (green). The dominant homozygous genotype is $RRYY$. In a Punnett square of $16$ squares,the genotype $RRYY$ appears only once. Therefore,the proportion of the dominant homozygous plants is $1/16$.

In Mendel's dihybrid cross,what is the proportion of the dominant homozygous plants in the $F_2$ generation (in $/16$)?
