Meiosis Prophase 1 progresses through Leptotene, Zygotene, Pachytene, Diplotene, and Diakinesis, involving chromosome condensation, synapsis, crossing over, and separation.
The stages of Prophase 1 in Meiosis are Leptotene (chromosome condensation, nucleus enlarges), Zygotene (synapsis begins, synaptonemal complex forms), Pachytene (synapsis complete, crossing over occurs via chiasmata), Diplotene (homologous chromosomes separate, linked by chiasmata), and Diakinesis (complete condensation, nucleoli disappear).
| Front | Stages of Prophase1 in Meiosis: |
|---|---|
| Back | 1)Leptotene Chromosomes start to condense, H. chromosomes move closer, "Nucleus size increases." 2)Zygotene Synapsis begins ie "Synaptonemal Complex" starts to form. 3)Pachytene Synapsis is completed, Chiasmata formation, Crossing over occurs. 4)Diplotene H. chromosomes begin to separate, connected only through Chiasma/chiasmata 5)Diakinesis Condensation is complete, separation of pairs is complete (united at just one point), Nuceloli disappear. |
