Question

Dissolution of synaptonemal complex occurs during

• A. Diplotene
• B. Leptotene
• C. Pachytene
• D. Zygotene

Answer 1

The correct option is A

Diplotene

The correct option is A.

Explanation of correct option:

1. Diplotene is fourth stage of the prophase of meiosis.
2. Characterized by chiasmata formation and dissolution of the synaptonemal complex.

Explanation of incorrect options:

Option B:

1. Leptotene is the first stage of the prophase of meiosis.
2. Involves longitudinal division of chromosomes to form sister chromatids.

Option C:

1. Pachytene is third stage of prophase of meiosis.
2. Involves crossing over of non-sister chromatids.
3. Characterized by recombination nodules.

Option D:

1. Zygotene is second stage of prophase of meiosis.
2. Involves formation of synaptonemal complex.

Final answer: Diplotene is characterized by the dissolution of synaptonemal complex.
