Process in which one parent cell divides to form two single cells? That process is called Mitosis in regular cells and Meiosis in sex cells or asexual reproduction. Edit
Mitosis. Mitosis is a form of eukaryotic cell division that produces two daughter cells with the same genetic component as the parent cell. Chromosomes replicated during the S phase are divided in such a way as to ensure that each daughter cell receives a copy of every chromosome. In actively dividing animal cells, the whole process takes about one hour.
