WebDuring anaphase, the sister chromatids separate and move to opposite ends of the cell. Lastly, during telophase, a nuclear envelope forms around each set of chromosomes, and the chromosomes start to uncoil. Then, cytokinesis occurs (however, it is not a phase of mitosis). During cytokinesis, the cytoplasm divides, creating two new daughter cells. WebGo to Section: Meiosis II Meiosis I results in two haploid (N) daughter cells, each with half the number of chromosomes as the original. Prophase II Metaphase II Anaphase II Telophase II The chromosomes line up in a similar way to the metaphase stage of mitosis. The sister chromatids separate and move toward opposite ends of the cell.
