Recall the main stages of meiosis: Prophase I, Metaphase I, Anaphase I, Telophase I, followed by Meiosis II stages (Prophase II, Metaphase II, Anaphase II, Telophase II).
Understand that during Prophase I, homologous chromosomes pair up and exchange genetic material through crossing over, but they do not separate yet.
During Metaphase I, homologous chromosome pairs align at the metaphase plate, preparing for separation.
In Anaphase I, the homologous chromosomes are pulled apart to opposite poles of the cell. This is the key phase where homologous chromosomes separate.
Note that Anaphase II involves the separation of sister chromatids, not homologous chromosomes, which distinguishes it from Anaphase I.
