Meiosis II is the second stage of the meiosis process, which is essential for producing gametes, such as sperm and eggs. It follows meiosis I and involves the separation of sister chromatids. This stage consists of four phases: prophase II, metaphase II, anaphase II, and telophase II, ultimately resulting in four haploid cells. During meiosis II, the chromosomes, which are already duplicated, align at the cell's equator. The sister chromatids are then pulled apart to opposite poles of the cell. After telophase II, the cells divide, leading to the formation of four genetically diverse haploid cells.
