  • What is the definition of meiosis?

    Meiosis is a form of nuclear division that produces haploid cells from diploid cells.

Meiosis Overview

Meiosis is a specialized type of nuclear division that reduces diploid cells to haploid cells, crucial for sexual reproduction in plants and animals.

Key Stages of Meiosis

  1. Meiosis I
  2. Divides homologous chromosomes.
  3. Stages: Prophase I, Metaphase I, Anaphase I, Telophase I.
  4. Meiosis II
  5. Divides sister chromatids.
  6. Stages: Prophase II, Metaphase II, Anaphase II, Telophase II.

Comparison with Mitosis

  • Meiosis has two rounds of division compared to one in mitosis.
  • Produces four non-identical haploid cells versus two identical diploid cells in mitosis.
