검증된 단계별 안내1
Recall the stages of meiosis I and meiosis II, focusing on the behavior of chromosomes during each phase.
Understand that during Prophase I, homologous chromosomes pair up and exchange genetic material through crossing over, but they do not separate yet.
Recognize that during Metaphase I, homologous chromosome pairs align at the metaphase plate, preparing for separation.
Identify that during Anaphase I, homologous chromosomes (each still consisting of two sister chromatids) are pulled apart and move toward opposite poles of the cell.
Note that Anaphase II involves the separation of sister chromatids, not homologous chromosomes, which occurs later in meiosis II.
