The dissolution of synaptonemal complex occurs during
Answer: (D) Diplotene. Answer: Diplotene Solution: The beginning of diplotene is recognised by the dissolution of the synaptonemal complex, with the recombined homologous chromosomes tending to separate except at the chiasmata.
- A.Diakinesis
- B.Leptotene
- C.Pachytene
- D.Diplotene✓
Correct Answer
(D) Diplotene
Solution & Explanation
Answer: Diplotene Solution: The beginning of diplotene is recognised by the dissolution of the synaptonemal complex, with the recombined homologous chromosomes tending to separate except at the chiasmata. Leptotene (chromosome visibility) and pachytene (recombination nodules) precede this, while diakinesis (terminalisation of chiasmata) follows it. NCERT Reference: Ch 10, p.126, lines 67-71 — "The beginning of diplotene is recognised by the dissolution of the synaptonemal complex"
