Guida verificata passo dopo passo1
Recall the stages of meiosis, which consists of two divisions: meiosis I and meiosis II. Each division has its own phases: prophase, metaphase, anaphase, and telophase.
Understand that during meiosis I, homologous chromosomes (each consisting of two sister chromatids) are separated, not the sister chromatids themselves.
Identify that in Anaphase I, homologous chromosomes move to opposite poles, but sister chromatids remain attached.
Recognize that sister chromatids separate during meiosis II, specifically in Anaphase II, where the centromeres divide and chromatids are pulled apart.
Therefore, the phase during which sister chromatids separate is Anaphase II.
