Asexual reproduction happens via mitosis. Why? Asexual reproduction implies that the organism does not combine its genetic material with that of another organism - It is a (“without”) - sexual (“fusion of gametes”). This means that for it to have offspring, it simply has to clone its own cells, much like in tissue repair. There is no need for genetic variability in offspring because we want to make clones, so no need for “crossing-over” or “independent assortment” as facilitated in meiosis with extra divisions. Furthermore, because we aren’t trying to create gametes (haploid), we can simply duplicate the DNA (Interphase), ready the cell for division (metaphase, anaphase, telophase) and divide the cell (cytokinesis). This produces diploid clones of the original parent cells: Mitosis: 46 (1 cell, diploid)-> 92 (1 cell) -> 46 x2 (2 cells, both diploid) As observed above, the basic steps of cell division observed in mitosis are sufficient. That’s all! *** Ps. Here is what happens in meiosis: 46 (1 cell, diploid) -> 92 (1 cell) -> 46 x2 (2 cells, both diploid) -> 23 x4 (4 cells (gametes), all haploid) ***
Mitosis: Sexual or Asexual? Mitosis is a form of asexual reproduction in simple living organisms. The outcome of each cell cycle is two identical cells. Mitotic checkpoints happen at certain stages of mitosis to ensure that each cell receives the same amount of DNA. Errors must be corrected or division halted because too many or too few chromosomes can harm the new cells. Sexual reproduction happens through meiosis. In the first phase of meiosis, matching chromosomes pair up and swap gene snippets. That's why children with the same parents may or may not look alike. Errors in meiosis can result in chromosomal abnormalities and disease when gene functioning is impaired. Why Mitosis Matters for Survival Many small organisms rely predominately on mitosis or a similar process like budding to stay alive and self-perpetuate. In larger organisms, mitosis plays a different kind of role in survival. All of the body’s non-reproductive cells divide by mitosis, such as skin cells, muscle cells and blood cells. Mitosis helps organisms grow, heal wounds and replace countless cells that are shed every minute.
Everything has been said below, just want to add: They are not exactly the same, as in asexual reproduction, a parent organism produces 2 identical daughter ORGANISMS. Whilst in mitosis, a parent cell produces 2 identical daughter CELLS. A fine detail but think it is important to note as they are not synonyms.

They would divide by mitosis. Examples include budding, hydras, vegetative propagation and strawberries.
