In Labrador Retrievers, a single gene controls whether an individual dog will be black or brown. Black labs have at least one copy of the dominant allele (B), while chocolate labs have two copies of the recessive allele (b). Imagine that you have a black lab of unknown genotype. Design a test cross that would enable you to determine its genotype.
