Guida verificata passo dopo passo1
Recall the stages of meiosis, which include Meiosis I and Meiosis II, each with their own phases: Prophase, Metaphase, Anaphase, and Telophase.
Understand that during Meiosis I, homologous chromosomes separate, but sister chromatids remain attached at their centromeres.
Recognize that the splitting of centromeres, which allows sister chromatids to separate, occurs during Meiosis II.
Identify that in Anaphase II, the centromeres split and sister chromatids are pulled apart toward opposite poles of the cell.
Conclude that the phase in which centromeres split and sister chromatids separate is Anaphase II.
