Understand that meiosis is a specialized type of cell division that reduces the chromosome number by half, producing haploid cells from a diploid precursor.
Recall that meiosis consists of two main stages: Meiosis I and Meiosis II, each involving a round of cell division.
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 cells from the original diploid cell.
Therefore, the total number of cell divisions in meiosis is two, which leads to the production of haploid cells.
