The type of cell division used when an organism reproduces asexually is binary fission. Only unicellular organism can undergo asexual reproduction and that is through the process of binary fission. Binary fission is the separation of the body into two new bodies. The genetic material is being duplicated and further divides into two through cytokinesis. Each of the new organism will possess one copy of the DNA. Multicellular organisms can also use mitosis to reproduce asexually.
