Question

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

• A. (ii), (iii), (iv), (i)
• B. (ii), (i), (iv), (iii)
• C. (ii), (i), (iii), (iv)
• D. (i), (ii), (iii), (iv)

Answer 1

The correct option is C (ii), (i), (iii), (iv)

The correct sequence is:-
Synapsis (Zygotene phase)
$\downarrow$
Crossing over (Pachytene phase)
$\downarrow$
Terminalisation of Chiasmata
$\downarrow$
Disappearance of Nucleolus
