In Labrador Retrivers, black fur (B) is dominat, brown fur (b)
is reccesive, and the phenotype yellow is controlled by a second
set of alleles. When another pair of alleles is present and is
homozygous recessive, cc, both black and brown pigments are
supressed and the dogs are yellow. Construct a Punnet Square and
provide the phenotype ratios of a dihybrid cross,BbCc* BbCc
