Match the following columns and select the correct option.

Meiosis I and II
NEET
1

A-(iv), B-(ii), C-(iii), D-(i)

2

A-(iii), B-(i), C-(iv), D-(ii)

3

A-(iv), B-(i), C-(iii), D-(ii)

4

A-(iii), B-(iv), C-(i), D-(ii)

Solution:

Let's match the events in Column-II with the stages of cell division in Column-I:

A. Metaphase II: In Metaphase II, the univalent chromosomes (each consisting of two sister chromatids) align at the equatorial plate. So, A matches (iv).

B. Diakinesis: Diakinesis is the final stage of Prophase I. During this stage, the nucleolus disappears, and the nuclear envelope breaks down. So, B matches (i).

C. Metaphase I: In Metaphase I, homologous chromosomes, which form bivalents, align at the equatorial plate. So, C matches (iii).

D. Diplotene: In Diplotene, the synaptonemal complex dissolves, and the homologous chromosomes start to separate, remaining attached only at the chiasmata. So, D matches (ii).

Therefore, the correct matching is:

A - (iv)

B - (i)

C - (iii)

D - (ii)

This corresponds to option (3).
