Recall that meiosis is a special type of cell division that reduces the chromosome number by half, producing haploid cells from a diploid cell.
Understand that meiosis consists of two consecutive divisions: meiosis I and meiosis II.
In meiosis I, homologous chromosomes are separated, reducing the chromosome number from diploid (2n) to haploid (n), but each chromosome still consists of two sister chromatids.
In meiosis II, the sister chromatids are separated, similar to mitosis, resulting in four haploid daughter cells in total.
Therefore, a single diploid cell divides twice during meiosis to produce four haploid daughter cells.
