The sister chromatids are separated during which phase of Meiosis II?

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

Answer: (C)

Verified step by step guidance

1. Understand the stages of Meiosis II: Meiosis II consists of four phases - Prophase II, Metaphase II, Anaphase II, and Telophase II.
2. Recall the role of sister chromatids: Sister chromatids are identical copies of a chromosome connected by a centromere, and they need to be separated into different cells.
3. Identify the phase where separation occurs: In Anaphase II, the centromeres split, and the spindle fibers pull the sister chromatids apart toward opposite poles of the cell.
4. Differentiate from other phases: In Metaphase II, sister chromatids align at the cell's equator, but they are not yet separated. In Prophase II, the cell prepares for division, and in Telophase II, the chromatids have already been separated and the cell is completing division.
5. Conclude that Anaphase II is the phase where sister chromatids are separated, as this is when the physical separation occurs due to the action of the spindle fibers.
