What occurs in meiosis but not mitosis? Mitosis and meiosis are specialized types of cell division, but take place in different locations. Mitosis occurs only in body cells, or somatic cells, while meiosis takes place in the cells of the testes and ovaries, which are the primary reproductive organs. Mitosis is triggered by the coupling of haploid sperm with a haploid egg; this coupling leads to fertilization.
