Explanation
Solution
A. Chiasmata formation : Chiasmata, the points where homologous chromosomes cross over, become visible during Diplotene. A-III
B. Crossing over : Crossing over, the exchange of genetic material between homologous chromosomes, occurs during Pachytene. B-I
C. Synaptonemal complex formation: The synaptonemal complex, a protein structure that facilitates homologous chromosome pairing, forms during Zygotene.C-IV
D. Terminalisation of chiasmata: Terminalisation, the movement of chiasmata towards the ends of the chromosomes, occurs during Diakinesis.D-II
