Which of the following stages of meiosis involves division of centromere?
Answer: (C) Anaphase II. Answer: Anaphase II Solution: The centromere (which holds the sister chromatids together) splits only at anaphase II in meiosis, allowing sister chromatids to move to opposite poles.
- A.Metaphase I
- B.Metaphase II
- C.Anaphase II✓
- D.Telophase
Correct Answer
(C) Anaphase II
Solution & Explanation
Answer: Anaphase II Solution: The centromere (which holds the sister chromatids together) splits only at anaphase II in meiosis, allowing sister chromatids to move to opposite poles. At anaphase I the centromeres do NOT divide — homologous chromosomes separate while sister chromatids stay attached at their centromeres. Metaphase I/II are alignment stages and involve no centromere division. NCERT Reference: Ch 10, p.127, lines 22-23 — "Anaphase II: It begins with the simultaneous splitting of the centromere"
