25% gray, 75% ebony 50% gray, 50% ebony 100% ebony 100% gray
I gave my students this multiple choice question: A male fruit fly is homozygous dominant for gray-body color (G) and is crossed with a female fruit fly that is homozygous recessive for ebony-body color (g). What are the probable phenotypes of the offspring?

Only one answer is correct among these 4 choices:
- 25% gray, 75% ebony
- 50% gray, 50% ebony
- 100% ebony
- 100% gray

Could you tell me which one is correct?

100% gray
