Presentation Transcript

  1. Meiosis Review

  2. Meiosis I: Replication

  3. Interphase I • DNA Replication • Chromatin a “ball of yarn”

  4. Prophase I • Chromosomes coil and condense • Form a tetrad (synapsis)

  5. Metaphase I • Tetrads align along equator

  6. Anaphase I • Tetrads split • Form dyads • Dyads move to opposite poles

  7. Telophase I • Cleavage furrow forms • Cell splits (cytokinesis) • Form two diploid daughter cells

  8. Meiosis II: Reduction Division

  9. Interkinesis • Similar to Interphase I • No DNA replication

  10. Prophase II • Chromosomes condense and coil

  11. Metaphase II • Chromosomes align along equator

  12. Anaphase II • Dyads split at centromere • Chromatids move to opposite poles

  13. Telophase II • Cleavage furrow forms • Cell splits • Both diploid cell splits • Forms 4 haploid daughter cells
