**Question:**A black Labrador Retriever is mated with a brown lab, but their offspring consists of black, brown AND golden labs. The two genes involved in producing this phenotype are a gene that controls pigment color and a gene that controls if pigment is deposited. This is an example of:- ○ Incomplete Dominance- ○ Pleiotropy- ○ Epistasis- ○ Multiple Alleles**Explanation:**In this genetic scenario, we are examining how the interaction between different genes affects the coat colors of Labrador Retrievers, demonstrating a concept in genetics known as "epistasis." Epistasis occurs when the expression of one gene is affected by another gene. This results in the observed variety of black, brown, and golden labs. The gene for pigment color and the gene for pigment deposition interact to produce these distinct phenotypes.

Step 1: Explaining the rational behind the appearance of different fur types in Labradors

Because here black and brown labradors mate to produce black, brown and yellow coloured Labrador offsprings this certainly means that fur colour Genetics in Labradors involve two separate genetic locus. Out of these probably one controls the pigment colour and the other decides whether the pigment is to be deposited or not.
