Aicharya · Accepted Answer

Tetrad formation occurs during the zygotene stage of meiotic prophase. Hence, statement A is not correct.

Anaphase stage is characterised by the following key events:

Centromeres split and chromatids separate.
Chromatids move to opposite poles.

Hence, statement B is correct.

Terminalisation of chiasma occurs during diplotene, after crossing over at pachytene, and terminalisation completion takes place in diakinesis. Hence, statement C is not correct.

During telophase, the nucleolus, endoplasmic reticulum (ER) and Golgi apparatus reappear. Hence, statement D is correct.

Crossing over is the exchange of chromosomal segments between non-sister chromatids of homologous chromosomes during the production of gametes. Hence, statement E is not correct.

Hence, option C is correct, i.e, statement B and D is correct.
