How many different types of gametes will be formed by a pea plant with genotype $TtYy$?

In Mendel's pea plants,round seeds $(RR)$ are dominant over wrinkled seeds $(rr)$,and yellow cotyledons $(YY)$ are dominant over green cotyledons $(yy)$. What will be the phenotypic ratio in the $F_2$ generation of a cross between $RRYY$ and $rryy$?

In a cross performed between parents considering two contrasting characters yellow round and green wrinkled seeds. In the $F_2$ generation progeny,the ratio of yellow and green will be . . . . . . .

In a trihybrid cross,which plant will produce eight types of gametes?

Mendel's law of independent assortment is based on the $F_2$ ratio of:

In a dihybrid cross,when $F_1$ plants $(RrYy)$ are self-hybridized,what is the segregation ratio of yellow and green seeds in the $F_2$ generation?
