In lab, the results do not exactly match the answer above. Your friend says it is because you messed up the cross and that if you had performed the cross correctly, your numbers would match your answer exactly. Is your friend correct? if not explain what's wrong with her logic?
Question 3: A study friend tells you that the genes in gametes can be homozygous or heterozygous. Is your friend correct or incorrect? If not, explain.s
