If two Labrador retrievers with the genotype BbEe were to be crossed...

The coat of Labrador retrievers is determined by two alleles. The black alleles, B, is dominant to the brown allele, b. A second pair of alleles, E and e, affects the expression of the coat colour, the homozygous recessive condition, ee, prevents the expression of black or brown and produces a pup with a yellow coat.

Genotype   Phenotype
