hair color is determined in labrador retrievers by alleles at the b and e loci. a dominant allele b encodes black pigment, whereas a recessive allele b encodes brown pigment. alleles at a second locus affect the deposition of the pigment in the shaft of the hair; dominant allele e allows dark pigment (black or brown) to be deposited, whereas recessive allele e prevents the deposition of dark pigment, causing the hair to be yellow. a black female labrador retriever was mated with a yellow male. half of the puppies were black and half were yellow. if the genotype of the black female parent was bb ee, then what was the genotype of the other parent?
