When Mendel self-hybridised the $F_{1}$ plants $(RrYy)$,he found that dominant and recessive traits of one character are segregated in a

The law of dihybrid cross proves which of the following?

In Mendel's experiments with garden pea,round seed shape $(RR)$ was dominant over wrinkled seeds $(rr),$ and yellow cotyledon $(YY)$ was dominant over green cotyledon $(yy).$ What are the expected phenotypes in the $F_{2}$-generation of the cross $RRYY \times rryy$?

$A$ human male produces sperms with the genotypes $AB, Ab, aB,$ and $ab$ pertaining to two diallelic characters in equal proportions. What is the corresponding genotype of this person?

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

In a dihybrid cross,what is the proportion of $RrYy$ offspring obtained from the selfing of an $RrYy$ plant (in $/16$)?
