Understand the phases of cell division: Mitosis and Meiosis are processes of cell division. Mitosis results in two identical daughter cells, while Meiosis results in four genetically diverse daughter cells.
Identify the stages of Mitosis and Meiosis II: Both processes include stages called prophase, metaphase, anaphase, and telophase. Anaphase is a critical stage where separation occurs.
Focus on Anaphase in Mitosis: During anaphase of mitosis, sister chromatids are pulled apart to opposite poles of the cell. This ensures that each daughter cell receives an identical set of chromosomes.
Examine Anaphase II in Meiosis II: Similar to mitosis, anaphase II in meiosis II involves the separation of sister chromatids. This is crucial for reducing the chromosome number by half, resulting in haploid cells.
Compare the events: In both anaphase of mitosis and anaphase II of meiosis II, the key event is the separation of sister chromatids. This is distinct from other processes like pairing of homologous chromosomes or crossing over, which occur in earlier stages of meiosis.
