검증된 단계별 안내1
Understand that meiosis consists of two sequential divisions: meiosis I and meiosis II, each with distinct stages.
Recall that during Metaphase I, homologous chromosome pairs (tetrads) align at the metaphase plate (center of the cell).
Recognize that in Prophase I, homologous chromosomes pair up and crossing over occurs, but they are not yet aligned at the center.
Note that in Anaphase I, homologous chromosomes separate and move toward opposite poles, so they are no longer at the center.
Understand that in Metaphase II, individual chromosomes (not homologous pairs) align at the center, as sister chromatids prepare to separate.
