3. In rabbits, spotted coat (S) is dominant to solid color (s) and black (B) is dominant to brown (b). These loci are unlinked. A homozygous true breeding brown spotted rabbit is mated to a solid black one, also from a pure line. Provide the phenotype and genotype for their offspring

Genotype: SsBb

Phenotype: Spotted, black

Explanation:

Homozygous, true-breeding brown spotted will have the genotype SSBB while a homozygous, true-breeding solid black rabbit will have the genotype ssbb.

Crossing the two to produce offsprin:

SSbb   x   ssBB  = All SsBb

All the offspring will have SsBb genotype and since S and B are dominant over s and b respectively, the offsprings will appear black and spotted.

See the attached Punnet's square analysis.
