Question

1 1 - - 1 Hair color is determined in Labrador retrievers by alleles at the Band 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. 1 1 1 1 1 -- A black female Labrador retriever was mated with a yellow male. 3/8 of the puppies were black 1/8 brown and half were yellow. If the genotype of the black female parent was Bb Ee, then what was the genotype of the other parent? I - - bb EE - - ВВ ее Bb ee bb ee BB EE

the answer I gave was wrong
