Task 5A. Define the term epistasis.B. Labrador retrievers have 3 varieties of fur colour: yellow, chocolate or black. Two genes areinvolved, each with a dominant (Y and B) and a recessive allele (y and b). The allele Ycodes for the ability to produce hair pigment: Yy and YY dogs have dark pigmented fur butall yy individuals are lighter coloured and yellow. The B allele codes for the ability to makehair with the darkest colouration: BB and Bb individuals have black fur, bb dogs have alighter shade which is chocolate. In the blank Punnet Square below, calculate and state theratio of phenotypes that occur with a cross between two individuals with the genotype YyBb.

Follow-up Question

Labrador retrievers have 3 varieties of fur colour: yellow, chocolate or black. Two genes are involved, each with a dominant (Y and B) and a recessive allele (y and b). The allele Y codes for the ability to produce hair pigment: Yy and YY dogs have dark pigmented fur but all yy individuals are lighter coloured and yellow. The B allele codes for the ability to make hair with the darkest colouration: BB and Bb individuals have black fur; bb dogs have a lighter shade which is chocolate. In the blank Punnet Square below, calculate and state the ratio of phenotypes that occur with a cross between two individuals with the genotype YyBb.
