Guida verificata passo dopo passo1
Understand the process of meiosis, which consists of two consecutive divisions: Meiosis I and Meiosis II. Each division has specific stages: Prophase, Metaphase, Anaphase, and Telophase.
Recall that during Meiosis I, homologous chromosomes are separated, not sister chromatids. This is a key distinction between Meiosis I and Meiosis II.
In Anaphase I, homologous chromosomes are pulled apart to opposite poles, but sister chromatids remain attached at their centromeres.
During Meiosis II, the separation of sister chromatids occurs. This is similar to mitosis, where the centromeres split and sister chromatids are pulled apart.
Identify that Anaphase II is the stage in Meiosis II where the centromeres of sister chromatids are separated, allowing them to move to opposite poles of the cell.
