WebNov 18, 2024 · Prophase II and Prometaphase II These stages are identical to their counterparts in meiosis I. Metaphase II In metaphase II, chromosomes line up in single file along the equator of the cell. This is in contrast to metaphase I, where chromosomes line up in homologous pairs. Figure 6 – Image of metaphase II Anaphase II WebIn prometaphase II, microtubules attach to the kinetochores of sister chromatids, and the sister chromatids are arranged at the midpoint of the cells in metaphase II. In anaphase II, the sister chromatids are separated. Telophase I and Cytokinesis In telophase, the separated chromosomes arrive at opposite poles.
