(A) In a dihybrid cross between $RRYY$ (round yellow) and $rryy$ (wrinkled green),the $F_{1}$ generation produces all $RrYy$ (round yellow) individuals.When $F_{1}$ individuals $(RrYy)$ are self-crossed to obtain the $F_{2}$ generation,the phenotypic ratio is $9:3:3:1$.The genotypic ratio for the $F_{2}$ generation is $1:2:1:2:4:2:1:2:1$.Specifically,the genotype $RrYy$ represents the double heterozygous condition.In the $16$ possible combinations of the Punnett square,the genotype $RrYy$ appears $4$ times.Therefore,the probability of obtaining $RrYy$ in the $F_{2}$ generation is $4/16$.

In a dihybrid cross between $RRYY$ and $rryy$,what is the probability of obtaining $RrYy$ in the $F_{2}$ generation (in $/16$)?
