Here's why:
* Mitosis: During anaphase of mitosis, the sister chromatids (identical copies of a chromosome) are pulled apart by the spindle fibers. This separation ensures that each daughter cell receives a complete set of chromosomes.
* Meiosis II: In anaphase II, the sister chromatids, which were already replicated in meiosis I, are separated. This process is similar to anaphase in mitosis, and results in four haploid daughter cells.
Important Note: In meiosis I, homologous chromosomes separate during anaphase I, not chromatids.
