The coat colour of some dogs is an example of an epistatic interaction. The common alleles are black (B) and brown (b). There is a separate gene on a separate chromosome that influences coat colour; it prevents colour formation and causes a white coat. L = prevents color formation and causes a white coat l = allows colour formation to occur. If a white dog heterozygous for both traits is crossed with a black dog that is heterozygous for the color gene,  which of the following represents the phenotypes of the offspring? Select one:
