Full Answer

Meiosis II is a process that includes prophase II, metaphase II, anaphase II, telophase II and cytokinesis. In prophase II, spindle fibers form inside the cells. Next, chromosomes align along the metaphase plate during metaphase II. In anaphase II, the chromosomes divide at their centromeres and migrate to each pole of the cell. During telophase II and cytokinesis, the chromosomes form four haploid nuclei, and the cells break apart to form four haploid cells.
