ReportQuestion
| Zygotene | Pachytene |
| The second stage in prophase 1 of meiosis, characterized by the synapsis, or pairing, of homologous chromosomes to form a bivalent. | The third stage of the prophase of meiosis during which the homologous chromosomes become short and thick and divide into four distinct chromatids. |
| Metaphase I | Metaphase II |
| Metaphase I is of much shorter duration and complexity in which tetrads align at the metaphase plate. The centromeres of homologous chromosomes are oriented toward the opposite cell poles. | The chromosomes become arranged on the metaphase plate, much as the chromosomes do in mitosis, and are attached to the now fully formed spindle. |
| Dikinesis | Cytokinesis |
| The final stage of the prophase in meiosis, characterized by shortening and thickening of the paired chromosomes, formation of the spindle fibers, disappearance of the nucleolus, and degeneration of the nuclear membrane. | Cytokinesisis the process whereby the cytoplasm of a single cell is divided to spawn two daughter cells |
