Detailed explanation-1: -The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase II, the chromosomes line up individually along the metaphase plate. In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell.
Detailed explanation-2: -Note: 10 chromosomes (each made of two sister chromatids) are present during the metaphase. The third phase of mitosis is called the metaphase and the process that separates the duplicated genetic material carried in the nucleus of the parent cell into 2 identical daughter cells.
Detailed explanation-3: -The spindle fibers will move the chromosomes until they are lined up at the spindle equator. Metaphase II: During metaphase, each of the 23 chromosomes line up along the center of the cell at the metaphase plate.
Detailed explanation-4: -There are 46 chromosomes in each cell at metaphase II in meiosis in humans. Normal human body cells each have 46 chromosomes. Prior to meiosis, the DNA replicates and each cell gets 92 chromosomes. Following the division in meiosis I, each cell has 46 chromosomes again.
