Recall the two main divisions in meiosis: Meiosis I and Meiosis II. Each has distinct events related to chromosome separation.
Understand that in Meiosis I, homologous chromosomes (each consisting of two sister chromatids) are separated, not the sister chromatids themselves.
In Anaphase I, homologous chromosomes move to opposite poles, but sister chromatids remain attached.
In Meiosis II, the sister chromatids finally separate. Specifically, during Anaphase II, the centromeres split and sister chromatids are pulled apart to opposite poles.
Therefore, the phase during which sister chromatids separate is Anaphase II.
