A rabbit is heterozygous for fur color. Black fur is dominant (B) and brown fur is recessive (b).Which describes the rabbit’s genotype and phenotype?

Heterozygous means the rabbit has two different alleles, so its genotype is Bb. Since black fur (B) is dominant over brown fur (b), a rabbit with genotype Bb has black fur. Therefore, the genotype is Bb and the phenotype is black fur.
