Match the following with respect to meiosis: (a) Zygotene - (i) Terminalization (b) Pachytene - (ii) Chiasmata (c) Diplotene - (iii) Crossing over (d) Diakinesis - (iv) Synapsis Select the correct option from the following

1. (a) (iv) (iii) (ii) (i)
2. (b) (i) (ii) (iii) (iv)
3. (c) (ii) (iv) (iii) (i)
4. (d) (iii) (iv) (i) (ii)

Correct answer: (a) (iv) (iii) (ii) (i)

Solution

In prophase I of meiosis, homologous chromosomes undergo synapsis during zygotene, crossing over during pachytene, chiasmata become visible in diplotene, and terminalization occurs in diakinesis. Therefore the correct matching is (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i).
