Arrange the following events of meiosis in correct sequence(i) Crossing over (ii) Synapsis(iii) Terminalisation of chiasmata(iv) Disappeara nce of nucleolus

The events of meiosis in correct sequence is:Synapsis→ Crossing over→ Terminalisation of chiasmata→ Disappearance of nucleolus.Synapsis occurs during zygotene, crossing-over takes place during pachytene, terminalization of chiasmata takes place during diakinesis and at last disappearance of nucleolus.
