Match the stages of meiosis in Column—I to their characteristic features in Column—II and select the correct option using the codes given below :

Column—I: a. Pachytene; b. Metaphase I; c. Diakinesis; d. Zygotene

Column—II: (i) Pairing of homologous chromosomes; (ii) Terminalization of chiasmata; (iii) Crossing-over takes place; (iv) Chromosomes align at equatorial plate

Codes :

a b c d

1. (i) (iv) (ii) (iii)

2. (ii) (iv) (iii) (i)

3. (iv) (iii) (ii) (i)

4. (iii) (iv) (ii) (i)

Best answer

Answer: 4. (iii) (iv) (ii) (i)

Each stage of meiotic prophase I has one signature event.

  • Pachytene: crossing-over between non-sister chromatids (iii).
  • Metaphase I: bivalents align at the equatorial plate (iv).
  • Diakinesis: chiasmata slide towards the ends, called terminalisation (ii).
  • Zygotene: homologous chromosomes pair up, forming the synaptonemal complex (i).

So a-iii, b-iv, c-ii, d-i, which is option 4.
