Question

Prophase of the first meiotic division is typically longer and complex. It is subdivided into $5$ phases: leptotene, zygotene, pachytene, diplotene and diakinesis. Which of the following statements is not correct of these phases?

• A. The formation of synaptonemal complex is seen during zygotene stage.
• B. The stage of pachytene is characterized by appearance of recombination nodules.
• C. Diplotene stage is marked by terminalisation of chiasmata.
• D. The compaction of chromosomes continues throughout the leptotene.

Answer 1

The correct option is C Diplotene stage is marked by terminalisation of chiasmata.

Meiosis is the type of division in which a diploid cell divides to give rise to four haploid gametes. The terminalization of chiasmata takes place during the diakinesis stage of meiosis, not j the diplotene stage.

So, the correct answer is 'Diplotene stage is marked by terminalisation of chiasmata.'
