A
It is recessive
B

Detailed explanation-1: -In rabbits, there are four different versions of the gene for coat color. What pattern of inheritance is this? multiple alleles.

Detailed explanation-2: -An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype.

Detailed explanation-3: -The two alleles in a gene pair are inherited, one from each parent. Alleles interact with each other in different ways. These are called inheritance patterns.

Detailed explanation-4: -Only individuals with an aa genotype will express a recessive trait; therefore, offspring must receive one recessive allele from each parent to exhibit a recessive trait.
