In Mendel's dihybrid cross,what is the probability of obtaining a homozygous recessive plant in the $F_2$ generation?

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 Mendel's dihybrid cross,what percentage of the $F_2$ generation possesses the $RrYy$ genotype (in $,\%$)?

$A$ pure tall plant with green pods is crossed with a pure dwarf plant with yellow pods. How many dwarf plants will be produced out of $16$ in the $F_2$ generation?

In Mendel's dihybrid cross,what percentage of the total $F_2$ progeny had green seeds (in $\%$)?

The phenotypic ratio of a dihybrid test cross performed by Mendel is ....
