Homozygous for both traits, the black furry rabbit is crossed with the same rabbit. Find the genotype and phenotype of the offspring if black dominates over white and shaggy fur over smooth fur.

Let’s designate the gene for black rabbit fur as K, then the gene for white fur will be k.

Let’s designate the gene for furry rabbit fur as L, then the gene for smooth fur will be l.

The homozygous black furry rabbit has, according to the introduced designations, the KKLL genotype. It is capable of producing only one type of egg – KL.

A rabbit with the same KKLL genotype produces the same type of KL sperm.

All offspring that can be obtained from crossing such rabbits will have black furry fur and a homozygous genotype identical to the genotypes of the parent individuals – KKLL.
