| Prophase I | The chromosomes condense, and the nuclear envelope breaks down. Crossing-over occurs. |
| Metaphase I | Pairs of homologous chromosomes move to the equator of the cell. |
| Anaphase I | Homologous chromosomes move to the opposite poles of the cell. |
| Telophase I | Chromosomes gather at the poles of the cells. |
| Cytokinesis | The cytoplasm divides. |
| Prophase II | A new spindle forms around the chromosomes. |
| Metaphase II | Metaphase II chromosomes line up at the equator |
| Anaphase II | Centromeres divide. Chromatids move to the opposite poles of the cells. |
| Telophase II | A nuclear envelope forms around each set of chromosomes. |
