WebCell Division Stages - Anaphase. In the anaphase, sister chromatids (meiosis II and mitosis) or homologous chromosomes (meiosis I) are pulled to opposite ends of the mother cell by the spindle fibres. Cell Division Stages - Telophase. During this stage, the chromatids or chromosomes reach opposite poles of the cell. WebMeiosis II happens in four stages: prophase II, metaphase II, anaphase II, and telophase II plus cytokinesis. During anaphase II, sister chromatids are separated. Meiosis II is a lot like mitosis, except that instead of two identical diploid daughter cells as in mitosis, meiosis II ends with four haploid, genetically different daughter cells.
