Explanation:
Detailed explanation-1: -A rabbit with the genotype of “BB” would have a phenotype of black fur, a genotype of “Bb” would have gray fur (a display of both black and white) and a genotype of “bb” would have a phenotype of white fur.
Detailed explanation-2: -According to the law of dominance, a trait is represented by two contrasting factors of a gene in a heterozygous individual while the homozygous individual carries two copies of same factors. Thus, the genotype of heterozygous rabbit will be Bb and that of homozygous recessive will be bb.
