Explanation:
Detailed explanation-1: -During meiosis I, homologous chromosomes, and in meiosis II, sister chromatids are segregated into daughter cells.
Detailed explanation-2: -The two “sister” chromatids are joined at a constricted region of the chromosome called the centromere. During cell division, spindle fibers attach to the centromere and pull each of the sister chromatids to opposite sides of the cell. Soon after, the cell divides in two, resulting in daughter cells with identical DNA.
