Answer

Brief Explanation:

If a black - furred mouse (assume black is dominant, B) is heterozygous (Bb) and is crossed with a white - furred mouse (bb, since white is recessive), the expected ratio of black to white offspring is 1:1 according to Mendelian genetics. Offspring ratios close to 1:1 or with some white offspring indicate the black - furred parent is heterozygous.

Answer:

B. 8 mice with black fur, 1 mouse with white fur C. 5 mice with black fur, 6 mice with white fur D. 6 mice with black fur, 2 mice with white fur
