  • Meiosis: How Cell Division Reduces Chromosome Number - A Comprehensive Guide
    Meiosis is a type of cell division that reduces the number of chromosomes in a cell by half. Here's how:

    * Starting Point: A normal cell has a diploid number of chromosomes (2n), meaning it has two copies of each chromosome.

    * Meiosis I: The first division separates the homologous chromosome pairs, resulting in two daughter cells, each with half the number of chromosomes (n) as the original cell.

    * Meiosis II: The second division separates the sister chromatids (identical copies of each chromosome) within each daughter cell, resulting in a total of four haploid cells (n).

    In summary: Meiosis takes a diploid cell (2n) and produces four haploid cells (n). This is crucial for sexual reproduction, as it ensures that offspring inherit one set of chromosomes from each parent.
