Understand that 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 that Meiosis I is characterized by the separation of homologous chromosomes, and it includes processes such as the formation of tetrads and crossing over between homologous chromosomes.
Recognize that Meiosis II is similar to mitosis and involves the separation of sister chromatids, not homologous chromosomes.
Identify that during Meiosis II, the sister chromatids are pulled apart to opposite poles of the cell, resulting in the formation of four genetically distinct haploid cells.
Conclude that the correct event occurring during Meiosis II is the separation of sister chromatids, distinguishing it from the events of Meiosis I.
