Tadpole's direct cell division, chromosome concentration, mitotic spindle formationwithout amassing. The nucleus membrane usually does not rupture, dividing into two parts by nuclear constriction or cleavage. After cytokinesis, two new cells are formed. Amitoz occurs in protozoa, some somatic cells, and in regeneration processes, for example, in liver cells. As a result, an equal distribution of genetic material and genetic variability can occur
