Meiosis
In meiosis are the cells produced from meiosis 1 AND meiosis 2 BOTH haploid?
would it therefore be correct to say that the duplicating of the DNA does not double the chromosome number; each chromosome in meiosis 1 consists of two sister chromatids that when seperated can also be considered as chromosomes? -
Re: Meiosis
Yes you are correct - after meiosis-I you have produced two N haploid cells from the original 2N cell. Each cell has 46 chromatids however it's still considered haploid - each chromosome is composed of two chromatids. During meiosis-II an anaphase reminiscent of mitosis occurs, splitting the sister chromatids, once again producing haploid cells where each chromosome now only consists of a single chromatid.
