Understand the process of meiosis, which consists of two stages: Meiosis I and Meiosis II. Each stage has its own phases: prophase, metaphase, anaphase, and telophase.
In Meiosis I, homologous chromosomes are paired together during prophase I, forming structures called tetrads.
During metaphase I, these tetrads align at the metaphase plate, preparing for separation.
Anaphase I is the phase where homologous chromosomes are pulled apart to opposite poles of the cell. This is the key event where homologous chromosomes separate.
In contrast, during anaphase II of meiosis and anaphase of mitosis, it is the sister chromatids that separate, not homologous chromosomes.
