Verified step by step guidance1
Understand that meiosis is a type of cell division that reduces the chromosome number by half, resulting in four daughter cells. It consists of two stages: Meiosis I and Meiosis II.
Recall that sister chromatids are identical copies of a chromosome connected by a centromere. They are crucial for genetic consistency during cell division.
In Meiosis I, homologous chromosomes (each consisting of two sister chromatids) are separated, not the sister chromatids themselves. This occurs during Anaphase I.
In Meiosis II, the sister chromatids are separated. This is similar to what happens in mitosis. The separation of sister chromatids occurs during Anaphase II.
Review the phases of Meiosis II: Prophase II, Metaphase II, Anaphase II, and Telophase II. Focus on Anaphase II, where the centromeres split and sister chromatids are pulled apart to opposite poles of the cell.
