- Meiosis
- Reduction Division...Important?
- Variation
- Homologous Pairs and Ploidy
- Haploid vs. Diploid Cells
- Meiosis: Reduction Division
- Two Divisions
- Replication of DNA: Two Sister Chromatids (Note: Only in Interphase 1)
- Independent Alignment of Homologous Chromosomes (Metaphase 1)
- Separation of Homologous Chromosomes (Anaphase 1)
- Meiosis 2: Separation of Sister Chromatids
- Crossing Over (Chiasma) and Production of Gametes
- Random Alignment and Crossing Over = Variation
- Recombination of Gametes = More variation
- Meiotic Errors
- Nondisjunction
- Aneuploidy and Polyploids
