Determine the number of possible gametes produced from an organism with the genotype $RrYy$.

In Mendel's dihybrid cross,the number of genotypes and phenotypes obtained in the $F_2$ generation are $P$ and $Q$ respectively. Identify $P$ and $Q$.

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?

In a dihybrid cross between $RRYY$ and $rryy$,the number of $RrYy$ $F_2$ genotypes will be

$A$ diploid organism is heterozygous for $4$ loci. How many types of gametes can be produced?

The following cross,$YyRr \times yyrr$ in garden pea plant,would result in the formation of
