Question

Diplotene stage of prophase - I is characterised by

• A. Dissolution of synaptonemal complex
• B. Separation of synapsed homologous chromosomes except at the site of crossovers
• C. Formation of X- shaped structures called chiasmata
• D. All of these

Answer 1

The correct option is D All of these

During the diplotene stage of prophase 1, chromosome begins to separate and terminalization starts. The crossing over that took place in the pachytene stage is now converted into the charismata which is a X like structure in the chromosome. The synaptonemal complex of the chromosomes that was formed now separates.

Thus, the correct answer is 'All of these.'
