What would be the genetic constitution

In rabbits, black is due to a dominant gene, B, and brown to its recessive allele, b. Short hair is due to a dominat gene, S, long hair to its recessive allele, s.

a) In a cross between a homozygous black shorthaired male and homozygous brown longhaired female, what would be the genetic constitution and appearance of the F1 generation?

b) Of the F2 generation?

c) In the F2 generation, what proportion of the black shorthaired rabbits would be homozygous for both pairs of genes?
