During which phase of meiosis II do sister chromatids separate?

• A. Telophase II
• B. Metaphase II
• C. Anaphase II
• D. Prophase II

Answer: (C)

Verified step by step guidance

1. Understand the process of meiosis II: Meiosis II is the second division in meiosis, where the sister chromatids of each chromosome are separated into different cells.
2. Review the phases of meiosis II: Prophase II, Metaphase II, Anaphase II, and Telophase II. Each phase has a specific role in the division process.
3. Focus on Anaphase II: During this phase, the sister chromatids are pulled apart by the spindle fibers and move toward opposite poles of the cell. This is the key event that distinguishes Anaphase II.
4. Compare with other phases: In Prophase II, chromosomes condense and spindle fibers form. In Metaphase II, chromosomes align at the metaphase plate. In Telophase II, the separated chromatids reach the poles, and the cell prepares to divide.
5. Conclude that the separation of sister chromatids occurs specifically during Anaphase II, making it the correct answer to the question.
