The end result of mitosis is two identical daughter cells.

Explanation:

Mitosis can be described as a process in which two new daughter cells are formed which are identical to the parent cells. The process of mitosis ensures that the daughter cells formed are similar to the parent cell. Hence, all the somatic cells of the body use mitosis for division.

On the other hand, meiosis can be described as a process in which four cells are formed which are not identical to the parent cells.
