Mendel’s second law, the Law of Independent Assortment, states that each trait assigned to offspring is done so without regard to any other trait assigned. In a dihybrid cross of two dogs, one that is black with a short tail and the other that is white with a long tail, the inheritance of one fur color is not dependent upon the inheritance of tail length. Assuming that black fur is dominant and a long tail is dominant and each parent is homozygous for each trait, how many offspring in the F2 generation will be white with a short tail?
