Key Points: Meiosis II

  1. Meiosis II is similar to mitosis and occurs in the two haploid cells formed after Meiosis I, dividing sister chromatids.
  2. It consists of four stages: Prophase II, Metaphase II, Anaphase II, and Telophase II.
  3. In Prophase II, chromosomes condense, and the nuclear membrane disappears.
  4. In Metaphase II, chromosomes align at the equator, and spindle fibres attach to kinetochores.
  5. In Anaphase II, centromeres split and sister chromatids move to opposite poles.
  6. In Telophase II, nuclear membranes reform and cytokinesis occurs.
  7. Final result: Formation of four haploid, genetically different daughter cells (tetrad), important for sexual reproduction (gametes/spores).
