NEET 2023 Phase 2 · BiologyMeiosis IPrevious Year Question

Select correct sequence of substages of Prophase-I of meiotic division: (A) Zygotene (B) Pachytene (C) Diakinesis (D) Leptotene (E) Diplotene

Answer: (A) (D), (A), (B), (E), (C). Answer: (D), (A), (B), (E), (C) Solution: Prophase I is subdivided into five sequential substages — Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis.

  1. A.(D), (A), (B), (E), (C)
  2. B.(A), (D), (B), (C), (E)
  3. C.(D), (B), (A), (E), (C)
  4. D.(A), (B), (D), (E), (C)

Correct Answer

(A) (D), (A), (B), (E), (C)

Solution & Explanation

Answer: (D), (A), (B), (E), (C) Solution: Prophase I is subdivided into five sequential substages — Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis. Matching these to the labels gives (D) Leptotene, (A) Zygotene, (B) Pachytene, (E) Diplotene, (C) Diakinesis, i.e. the sequence (D),(A),(B),(E),(C). NCERT Reference: Ch 10, p.126, lines 22-23 — "Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis"
