Process by which a eukaryotic cell divides its nucleus and contents, resulting in two genetically identical daughter cells
Phases of Meiosis
1. Meiosis I: Prophase I
2. Metaphase I
3. Anaphase I
4. Telophase I
5. Meiosis II: Prophase II
6. Metaphase II
7. Anaphase II
8. Telophase II
Meiosis
Two-stage division process that reduces the chromosome number by half, resulting in four genetically unique haploid cells
If non-disjunction occurs in meiosis II, sister chromatids fail to separate properly
Results of Non-Disjunction in Meiosis II
Aneuploid Gametes: One gamete may have an extra chromosome (n+1), and one gamete may have one less chromosome (n-1). The other two gametes will have the normal haploid number of chromosomes.
