Chromosomes line up with their centromeres on the equator during metaphase of any eukaryotic cell division: mitosis, meiosis I, or meiosis II.

During metaphase the arms of the chromosomes are spread out, but it will be the centromeres that lead the way towards the poles during anaphase. This is because in metaphase some spindle fibers, which are formed by the cytoskeleton, attach to the centromeres. It is the contraction of these fibers that pulls the chromosomes (daughter-chromosomes in mitosis and meiosis II) towards the poles in anaphase.

There is an important checkpoint during metaphase. If the spindle fibers are not correctly attached, division should stop. However, a few mistakes slip through the net, and sometimes both daughter-chromosomes of a pair (in other words, a pair of former sister-chromatids) move to the same pole. This phenomenon is called non-disjunction, and leads to an abnormal number of chromosomes in both daughter-nuclei.
