Verified step by step guidance1
Understand the stages of meiosis: Meiosis consists of two rounds of division, meiosis I and meiosis II. Each has its own phases: prophase, metaphase, anaphase, and telophase.
Recall the events of anaphase I: During anaphase I of meiosis, homologous chromosomes are separated and pulled to opposite poles of the cell. This is different from mitosis, where sister chromatids are separated.
Focus on anaphase II: In meiosis II, the process resembles mitosis. During anaphase II, the sister chromatids are separated. This is a key distinction from anaphase I.
Identify the structures involved: Sister chromatids are identical copies of a single chromosome that are connected by a centromere. During anaphase II, the centromeres split, allowing the sister chromatids to be pulled apart.
Conclude with the correct answer: Based on the understanding of meiosis II, the structures pulled apart during anaphase II are the sister chromatids.
