Question

Terminal chiasmata are seen during which phase of meiosis
Options
A Anaphase I
B Prophase I
Correct Answer
C Metaphase I
D Metaphase II
Correct Answer

Option B is the correct answer.

Detailed Explanation

Chiasmata are the visible points of contact between non-sister chromatids where crossing over has occurred. They are most clearly seen during the diplotene stage of Prophase I, where they appear to 'terminalize' (move towards the ends of the chromosomes) as prophase progresses.

Hint

In which phase of meiosis do homologous chromosomes pair up and crossing over occur?
