What type of gametes will be formed by the genotype $RrYy$?

$A$ double heterozygous tall plant with yellow cotyledon colour is selfed. What is the ratio of dwarf plants with green cotyledon in the offspring?

In the $F_2$ generation of a Mendelian dihybrid cross,how many plants homozygous for both the traits are found?

$A$ trihybrid cross involves three pairs of traits,which gives an $F_1$ hybrid that is heterozygous for three genes. How many types of gametes will be produced in both male and female?

When a tall plant with rounded seeds $(TTRR)$ is crossed with a dwarf plant with wrinkled seeds $(ttrr)$,the ${F_1}$ generation consists of tall plants with rounded seeds. How many types of gametes will an ${F_1}$ plant produce?

$A$ pure breeding pea plant with round yellow seeds was crossed with a pea plant having wrinkled green seeds. On selfing of the $F_1$ hybrid of this cross,$64$ progenies were obtained in the $F_2$ generation. Find out the number of $F_2$ progenies showing non-parental characters.
