75% Rr, 25% rr 50% Rr, 50% rr 100% Rr 100% rr
I gave my students this multiple choice question: When crossing parents with genotypes Rr and rr, what will be the percentages of the genotypes of the offspring?

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

Could you tell me which one is correct?

50% Rr, 50% rr
