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

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

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

Find out the frequency of $AabbCcDdee$ if parents are $AabbCCddEe$ and $AabbccDdee$. (in $\%$)

$A, B, D$ are three independently assorting genes with their recessive alleles $a, b, d$,respectively. $A$ cross was made between individuals of $Aa bb DD$ genotype with $aa bb dd$. Find out the types of genotypes of the offspring produced.

If the cross is $Aabb \times aaBb$,what will be the genotypic ratio of the offspring?
