I gave my students this multiple choice question: A mouse is homozygous for black fur (BB). The other parent is heterozygous for black fur with a recessive trait for brown fur ( Bb ). If black is the dominant trait, what percentage of the offspring will be brown?

Only one answer is correct among these 4 choices:
- 100%
- 50%
- 25%
- 0%

Could you tell me which one is correct?
