Labrador coat colour is controlled by two genes:Gene 1: Controls whether pigment will be expressed Allele E - dominant and codes for pigment production Allele e - recessive and codes for no pigment production (dogs will always be yellow)Gene 2: Controls which pigment is expressed Allele B - dominant and codes for black fur Allele b - recessive and codes for brown furWhat would be the ratio of the phenotypes of the offspring if two black dogs who were heterozygous for both genes reproduced?
