| Question | Answer |
|---|---|
| Prophase I | homologous chromosomes condense and pair up during synapsis; spindle fibers form; crossing over |
| Metaphase I | pairs of homologous chromosomes line up at the cells equator |
| Anaphase I | homologous chromosomes separate and move towards opposite ends of the cell |
| Telophase I | homologous chromosomes reach the cells poles and cytokinesis usually occurs |
| Prophase II | spindle apparaus forms; chromosomes condense |
| Metaphase II | chromosomes line up at the cell's equator |
| Anaphase II | sister chromatids are pulled apart by the spindle fibers and move toward opposite ends of the cell |
| Telophase II | Chromosomes reach the cells poles, the nuclear membrane and nuclei re-form and cytokinesis occurs; four cells form |
