Verified step by step guidance

Recall the stages of meiosis, which consists of two divisions: meiosis I and meiosis II, each with prophase, metaphase, anaphase, and telophase phases.

Understand that during meiosis I, homologous chromosomes (each consisting of two sister chromatids) pair up and then separate, while during meiosis II, sister chromatids separate.

Identify that in Metaphase I, homologous chromosomes line up at the metaphase plate, preparing for separation.

Recognize that in Anaphase I, the homologous chromosomes are pulled apart and move toward opposite poles of the cell.

Note that Anaphase II involves the separation of sister chromatids, not homologous chromosomes, so the correct phase for homologous chromosome separation is Anaphase I.
