Guida verificata passo dopo passo1
Recall the stages of meiosis, which consists of two divisions: Meiosis I and Meiosis II, each with its own phases (Prophase, Metaphase, Anaphase, Telophase).
Understand that during Meiosis I, homologous chromosomes separate, while sister chromatids remain together.
Identify that the separation of sister chromatids occurs during Meiosis II, which resembles mitosis.
Focus on Anaphase II, the phase in Meiosis II where sister chromatids are pulled apart and move to opposite poles of the cell.
Conclude that the correct phase for sister chromatid separation is Anaphase II, not Anaphase I or Metaphase II.
