In Mendel's dihybrid cross experiment,when $F_1$ generation plants are self-pollinated,what is the proportion of each type of gamete produced (in $\%$)?

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 of the $F_1$ generation when a homozygous round yellow plant $(RRYY)$ is crosseded with a homozygous wrinkled green plant $(rryy)$?

$A$ human male is heterozygous for autosomal genes $A$ and $B$ and is also hemophilic (gene $h$). What proportion of his sperm will contain the $abh$ gene combination?

In the $F_2$ generation of Mendel's dihybrid cross,which phenotype is observed with the highest frequency?

The law of dihybrid cross proves which of the following?
