Detailed explanation-1: -The coat colour of rabbits is expressed through incomplete dominance. The coat colour can be dark brown, light brown, or white. There are 81 dark brown rabbits, 150 light brown rabbits, and 69 white rabbits.

Detailed explanation-2: -An example of multiple alleles is coat color in rabbits (Figure 1). Here, four alleles exist for the c gene. The wild-type version, C+C+, is expressed as brown fur.

Detailed explanation-3: -All the other rabbit colors that you may see, are due to the influence of the other genes. “B” is usually used to reference the Black gene. This gene is the most dominant of the two genes, so a rabbit can show a black color, but carry the brown gene.

Detailed explanation-4: -Fur color follows a pattern of incomplete dominance because black fur is not dominant in Chinchilla and Himalayan rabbits. Fur color is codominant since four different phenotypes are observed. Fur color involves multiple alleles since four different phenotypes are observed.

Detailed explanation-5: -How is coat color in rabbits inherited? Coat color in rabbits is inherited as a series of multiple alleles. This means that there can be more than just 2 alleles for a single gene. In the case of coat color in rabbits, there are four alleles, and each one is expressed with a different phenotype.
