Anaphase I

Telophase I

Anaphase II

Metaphase II

Verified step by step guidance

Recall the key events of meiosis I and meiosis II, focusing on what happens to the chromosomes and their centromeres during each stage.

Understand that during Anaphase I, homologous chromosomes (each consisting of two sister chromatids) are pulled to opposite poles, but the centromeres do not split at this stage.

Recognize that the splitting of centromeres, which separates sister chromatids, occurs during Anaphase II, allowing the chromatids to migrate to opposite ends of the cell.

Note that Telophase I involves the reformation of the nuclear membrane around the separated homologous chromosomes, but no centromere splitting occurs here.

Confirm that Metaphase II is the stage where chromosomes line up at the metaphase plate, but centromere splitting and migration happen in the subsequent Anaphase II.
