For mice that are either homozygous dominant (PP) or heterozygous (Pp), the organism's fur color is dictated by the other three
julsineya [31]

Answer:

The answer is 1/4 of the offspring will have solid color, 3/4 of the offspring will have black fur,  3/4 will probably have colored fur, and 1/4 of the mice offspring wil probably have pieblad, or white patches. The combined probability is  1/4 X 3/4 X 3/4 X 1/4 = 9/256.

Explanation:

Because each gene segregates independently, so you need to determime the probability of each genotype independently and then multiply the four probabilities together. The probability of offspring with solid color (aa) is 1/4; the probality of offspring  with black fur (BB or Bb) is 3/4; the probability of colored fur (Cc or cc) is 3/4, and the probability of piebald, or white patches(pp), is 1/4.   The combined probability is  1/4 X 3/4 X 3/4 X 1/4 = 9/256.
