Recall the stages of meiosis I and their key events, focusing on what happens during anaphase I.
Understand that during anaphase I, homologous chromosomes (each consisting of two sister chromatids) are separated and pulled to opposite poles of the cell.
Differentiate this from anaphase II, where sister chromatids are separated, and from metaphase I, where chromosomes align along the metaphase plate.
Note that the nuclear envelope does not reform during anaphase I; it typically reforms after telophase II.
Conclude that the correct description of anaphase I is the separation and movement of homologous chromosomes to opposite poles.
