I gave my students this multiple choice question: In mice, a certain species displays incomplete dominance in coat coloring. The offspring of a black (BB) mouse and a white (bb) mouse are gray (Bb) mice. A cross between two gray mice will most likely produce offspring with which percent of coat colors?

Only one answer is correct among these 4 choices:
- 25% black, 75% gray
- 25% gray, 75% white
- 25% white, 25% black, 50% gray
- 25% gray, 25% black, 50% white

Could you tell me which one is correct?

25% white, 25% black, 50% gray
