  • Mitosis vs. Meiosis: Key Differences & Characteristics
    Here are some key characteristics that differentiate mitosis from meiosis:

    Mitosis

    * Purpose: Growth, repair, and asexual reproduction in single-celled organisms.

    * Number of divisions: One division, resulting in two daughter cells.

    * Number of chromosomes in daughter cells: Same number of chromosomes as the parent cell (diploid).

    * Genetic material: Daughter cells are genetically identical to the parent cell.

    * Crossing over: Does not occur.

    * Synapsis: Does not occur.

    * Homologous chromosomes: Do not pair up.

    * Cell type: Occurs in somatic cells (all cells except gametes).

    Meiosis

    * Purpose: Production of gametes (sex cells) for sexual reproduction.

    * Number of divisions: Two divisions, resulting in four daughter cells.

    * Number of chromosomes in daughter cells: Half the number of chromosomes as the parent cell (haploid).

    * Genetic material: Daughter cells are genetically different from the parent cell and from each other due to crossing over and independent assortment.

    * Crossing over: Occurs during prophase I, exchanging genetic material between homologous chromosomes.

    * Synapsis: Homologous chromosomes pair up during prophase I.

    * Homologous chromosomes: Pair up during prophase I.

    * Cell type: Occurs in germ cells (cells that give rise to gametes).

    In a nutshell: Mitosis produces two identical daughter cells, while meiosis produces four genetically diverse daughter cells with half the number of chromosomes.
