Question

Arrange the following events of meiosis in a correct sequence:
I. Crossing over
II. Synapsis
III. Terminalisation of chiasmata
IV. Disappearance of nucleolus

Accepted Answer

The correct sequence of events during Prophase I of Meiosis is:
1. Synapsis (II): Occurs during the Zygotene stage, where chromosomes start pairing together.
2. Crossing over (I): Occurs during the Pachytene stage, involving the exchange of genetic material.
3. Terminalisation of chiasmata (III): Occurs during Diakinesis, where chiasmata shift towards the ends of the chromosomes.
4. Disappearance of nucleolus (IV): Happens by the end of Diakinesis, marking the transition to Metaphase I, , .
