What is the genotype of the $F_1$ generation offspring obtained in a dihybrid cross?

$A$ human male produces four types of gametes $AB, Ab, aB,$ and $ab$ in equal proportions. What is the corresponding genotype of this individual?

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 $\%$)?
