In prophase II the chromosomes again supercoil and in metaphaseII they align at the equator and are joined by microtubules from the centrioles at the poles. The microtubules join to the centromeres and pull apart the chromatids
During anaphase II the chromatids are pulled to the poles of the cell.
Then telophase II forms a new nuclear membrane around the chromatids to form two new nuclei
This means 4 haploid cells have been formed from
2 haploid cells in meiosis II. These cells will become sex cells (gametes).
