Question

Which stage is marked by terminalisation of chiasmata?

• A. pachytene
• B. zygotene
• C. diakinesis
• D. diplotene

Answer 1

The correct option is C diakinesis

$\text{Chiasmata}$

Chiasmata are structures formed between a pair of homologous chromosomes by the process of crossover recombination. These structures physically link the homologous chromosomes during meiosis.

$\text{Diakinesis}$

During diakinesis, the chiasmata shifts towards the chromosome ends. This is known as terminalisation. The nucleolus and nuclear envelope also disintegrate during this stage.

$\text{Final answer}$

(d) diakinesis
