The number of phenotypic recombinant offspring formed during the $F_2$ generation of a dihybrid cross is . . . . . . . (in $1/16$)

In rabbits,black skin $(B)$ is dominant over brown skin $(b)$ and short hair $(S)$ is dominant over long hair $(s)$. $A$ homozygous black,short-haired male is crossed with a homozygous brown,long-haired female. All $F_1$ offspring are heterozygous black,short-haired. If the $F_1$ male is crossed with an $F_1$ female,what is the percentage of homozygous black,short-haired offspring in the $F_2$ generation (in $\%$)?

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

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.

$A$ dihybrid plant produced by self-pollination yields $400$ seeds with $9$ different genotypes. How many seeds will have the $TtRr$ genotype?

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