Anaphase II
C
Telophase I
D
Anaphase I
Verified step by step guidance1
Recall the stages of meiosis, which consists of two divisions: Meiosis I and Meiosis II, each with its own phases (Prophase, Metaphase, Anaphase, Telophase).
Understand that in Meiosis I, homologous chromosomes separate, while in Meiosis II, sister chromatids separate.
Identify that during Anaphase I, homologous chromosomes move to opposite poles, but sister chromatids remain together.
Recognize that during Anaphase II, sister chromatids finally separate and move to opposite poles of the cell.
Conclude that the stage where sister chromatids separate and move to opposite poles is Anaphase II.
