Chromosome number unchanged

The question reads, "the chromosome number remains unchanged as a result of?"

The correct answer is mitosis because for obvious reasons- daughter cells having 2n just like the parent cell.

But wouldn't meiosis be correct as well? If you think about it, meiosis is a reductive division that yields haploid gametes and as a result of this reduction, fertilization yields the diploid zygote conserving the original number of chromosomes.

The way I pictured this was envisioning meiosis that didn't have a reductive process which would yield a zygote with double the number of original chromosomes. If this were to happen, chromosome number would indeed change, but since meiosis is reductive division, it ultimately conserves original chromosome number?

Am I missing something here?😕

I understand your question. you have to be careful how the question is wording. for example if the question ask you" what is the purpose of Miosis mechanism" you answer would be the "chromosome number remains unchanged"

I think that you mean meiosis one, but meiosis 2 yields 23 chromosomes?

Meiosis does not include fertilization. After meiosis there are only 23 chromosomes. True it reverts back to 46 by fertilzation but that has nothing to do with meiosis.

jdent,

the "reductive division" would actually be in meiosis I.
