What is not the incorrect sequence of prophase I of meiosis?
Options
- ALeptotene, pachytene, zygotene, diakinesis, diplotene
- BDiplotene, leptotene, pachytene, zygotene, diakinesis
- CDiakinesis, diplotene, leptotene, zygotene, pachytene
- DLeptotene, zygotene, pachytene, diplotene, diakinesis
Correct answer
D. Leptotene, zygotene, pachytene, diplotene, diakinesis
Step-by-step solution
Prophase I of meiosis is of longest duration and is further subdivided into five sub phases: leptotene, zygotene, pachytene, diplotene, diakinesis. Leptotene shows bouquet formation. The pairing of homologous chromosome or synapsis occurs in zygotene. Crossing over occurs in pachytene. Chiasmata formation occurs in diplotene, and terminalisation occurs in diakinesis.
