    So I'm reading my bio book, it says the first division is reduction division, so cells go from diploid to haploid. I then read on and it says the second division produces four haploid cells, but if it divides twice doesn't that produce 1/4. I thought that it might be that it replicates before dividing the second time, but it doesn't mention it anywhere, I'm so confused??

    The first division goes from diploid to haploid because each of the daughter cells has half the number of chromosomes as the parent cell; 1 chromosome from each homologous pair.

    The second division also produces haploid cells because it isn't homologous pairs that are splitting, it's the chromosomes themselves. The 2 chromatids that make up a chromosome split and become 2 independent chromosomes, so the daughter cells have the same number of chromosomes as the parent cell.

    I see, so chromosomes in the four cells are made from 1 chromatid, while chromosomes in the two cells are made of 2 chromatids, but because they have the same number of chromosomes they are both haploid. Thanks!!

    I'm glad it helped you. I was struggling to get my head around meiosis and found it helped to explain it very well.
