NEET 2023 Phase 2 · BiologyMeiosis IPrevious Year Question
Dissolution of the synaptonemal complex occurs during:
Answer: (A) Diplotene. Answer: Diplotene Solution: Diplotene begins with the dissolution of the synaptonemal complex, after which the recombined homologous chromosomes tend to separate except at chiasmata.
- A.Diplotene✓
- B.Leptotene
- C.Pachytene
- D.Zygotene
Correct Answer
(A) Diplotene
Solution & Explanation
Answer: Diplotene Solution: Diplotene begins with the dissolution of the synaptonemal complex, after which the recombined homologous chromosomes tend to separate except at chiasmata. The synaptonemal complex actually forms during zygotene (with synapsis); leptotene only makes chromosomes visible; pachytene is when crossing over occurs. Hence dissolution happens at diplotene. NCERT Reference: Ch 10, p.126, lines 67-72 — "diplotene is recognised by the dissolution of the"
