NEET 2023 Phase 1 · BiologyPloidyPrevious Year Question

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.

  1. A.Metaphase I
  2. B.Metaphase II
  3. C.Anaphase II✓
  4. 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"
