Question

During meiosis chromatids of individual chromosome seperate during

• A. Metaphase I
• B. Anaphase I
• C. Anaphase II
• D. Metaphase II

Answer 1

The correct option is D Metaphase II

During metaphase II, the spindle fibers get attached to the centromere of a chromosome from both sides. Therefore, the centromere divides and two chromatids of each chromosome separate and move towards the poles during anaphase II.
In Metaphase I, the spindle fibers get attached to two centromeres of each homologous chromosome and the two chromosomes repel each other and move towards the opposite poles. Hence, a division in centromere is not observed during this stage.
