During metaphase II, the centromeres of the paired chromatids align along the equatorial plate in both cells. Then in anaphase II, the chromosomes separate at the centromeres. The spindle fibers pull the separated chromosomes toward each pole of the cell.
Mitosis is the cell division process that occurs anywhere in the body, these except the production of the gametes.
If the cells were more in the mitotic process then the cells would only keep dividing in an amassing rate. This might cause some genetic errors and dysfunctions.
