Verified step by step guidance1
Understand that meiosis is a special type of cell division that reduces the chromosome number by half, producing haploid cells from a diploid germ cell.
Recall that meiosis consists of two main stages: Meiosis I and Meiosis II, each involving one round of cell division.
In Meiosis I, homologous chromosomes separate, 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 separate, 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 is the key to producing haploid cells from a diploid germ cell.
