Understand the context of meiosis: Meiosis is a type of cell division that reduces the chromosome number by half, creating four haploid cells. It consists of two stages: meiosis I and meiosis II.
Recall the phases of meiosis II: Meiosis II is similar to mitosis and includes prophase II, metaphase II, anaphase II, and telophase II.
Focus on anaphase II: During anaphase II, the sister chromatids, which were previously duplicated during interphase, are separated.
Describe the movement of chromatids: The sister chromatids are pulled apart by the spindle fibers and move toward opposite poles of the cell.
Clarify the outcome: The separation of sister chromatids ensures that each daughter cell receives an equal number of chromosomes, resulting in four genetically distinct haploid cells at the end of meiosis II.
