How many phenotypes can be obtained if a pea plant $(RrTt)$ is crossed with another pea plant with the same genotype?

$A$ 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 a cross between yellow round $(YYRR)$ and green wrinkled $(yyrr)$ pea plants,find out the ratio between seeds having yellow and green seed colour in the $F_{2}$ generation.

In plants,red fruit $(R)$ is dominant over yellow fruit $(r)$ and tall height $(T)$ is dominant over dwarf height $(t)$. If a plant with genotype $RRTt$ is crossed with a plant with genotype $RRTt$,what will be the phenotype of the offspring?

The following experiment is a dihybrid cross performed by Mendel. In which of the following are the green and wrinkled traits observed in the pea plants?

If $AAbb \times aaBB$,then the phenotypic ratio of its $F_{2}$ progeny will be
