If the number of chromosomes were not reduced during meiosis, how many chromosomes would a human gamete have? How many chromosomes would result after fertilization?
I sort of get it, but I would like a better understanding/explanation of this.

This is a tough one to answer. Normally what happens is that the 46 you have double to 92. Then, after meiosis 1, it reduces to 46, and after meiosis 2 it reduces to 23.

It's hard to tell if the question wants NO reduction at all. In that case, you'd say 92 -- double the chromosomes. Or do they want us to assume meiosis one DID occurr, and say 46 instead?

Once again, problematic to say anything. If we assume 92 from the previous question, and it combines with another mutant gamete containing 92, that's 184 chromosomes! Or if we assumed 46, and it combined with another mutant 46, it'd make 92 after fertilization.

Reminder that this would never happen in nature

Is your understanding the same, whatchu think?
