  • Prophase: Chromosomes condense, and the nuclear membrane dissolves.

  • Metaphase: Chromosomes align at the metaphase plate.

  • Anaphase: Sister chromatids separate.

  • Telophase & Cytokinesis: Two genetically identical diploid daughter cells form.

    1. Prophase I: Crossing-over occurs, where homologous chromosomes exchange genetic material.

    2. Metaphase I: Homologous pairs line up randomly (independent assortment).

    3. Anaphase I: Homologous chromosomes (not sister chromatids) separate.

    4. Telophase I & Cytokinesis: Two haploid (n) cells form.

    Meiosis II

    (similar to mitosis but with half the chromosomes)

    5. Prophase II: Chromosomes condense again.
    6. Metaphase II: Chromosomes align.
    7. Anaphase II: Sister chromatids separate.

    8. Telophase II & Cytokinesis: Four haploid (n) daughter cells form.

    • Crossing-over in Prophase I allows homologous chromosomes to exchange genetic material.

    • Independent assortment in Metaphase I randomly arranges maternal and paternal chromosomes, leading to different genetic combinations.

This occurs because each homologous pair aligns randomly at the metaphase plate during Metaphase I, ensuring unique genetic combinations in offspring.
