In which division of meiosis do chromosomes split at the centromere and sister chromatids are separated?

• A. Meiosis II
• B. Interphase
• C. Cytokinesis
• D. Meiosis I

Answer: (A)

Verified step by step guidance

1. Recall that meiosis consists of two main divisions: Meiosis I and Meiosis II, each with distinct events.
2. Understand that during Meiosis I, homologous chromosomes are separated, but sister chromatids remain attached at the centromere.
3. Recognize that the separation of sister chromatids at the centromere occurs during Meiosis II, similar to mitosis.
4. Identify that the splitting of chromosomes at the centromere and the separation of sister chromatids is the defining event of Meiosis II.
5. Conclude that the correct division where chromosomes split at the centromere and sister chromatids separate is Meiosis II.
