Anaphase II

Anaphase II

• A. Chromosomes line up in the center
• B. Four haploid daughter cells are produced
• C. Paired chromatids separate
• D. DNA is replicated

Answer: (C)

Anaphase II is the stage in meiosis II when the sister chromatids split apart at the centromeres and are pulled toward opposite poles. The shortening of kinetochore microtubules pulls the two chromatids away from each other, so they become separate chromosomes that move to opposite ends of the cell. That’s why the statement about paired chromatids separating is the best fit for this stage. Think of where this fits in the sequence: mitotic-like separation of sister chromatids happens here, not the lining up at the center, which is metaphase II. The final production of four haploid daughter cells occurs after cytokinesis, the end of meiosis II, not during anaphase II. And DNA replication happens earlier, during interphase before meiosis begins, not during anaphase II.
