Understand the context of meiosis: Meiosis is a type of cell division that reduces the chromosome number by half, creating four haploid cells. It consists of two stages: meiosis I and meiosis II.
Recall the events of meiosis I: During meiosis I, homologous chromosomes are separated into two different cells. This is the reductional division where the chromosome number is halved.
Focus on meiosis II: Meiosis II is similar to mitosis, where the sister chromatids are separated. This is the equational division, maintaining the chromosome number in each cell.
Identify the phase: Anaphase II is a stage in meiosis II where the sister chromatids are pulled apart by the spindle fibers towards opposite poles of the cell.
Clarify the separation: During anaphase II, the centromeres split, allowing the sister chromatids to separate and move to opposite ends of the cell, resulting in the formation of individual chromosomes.
