What is the difference between Mitosis and Meiosis?

Mitosis occurs in all human cells, producing two genetically identical daughter cells containing a full set of chromosomes (diploid). This process takes place to replace old cells, in wound healing and in growth. Meiosis on the other hand only takes place in sex cells (gametes) and results in half the number of chromosomes in each cell (haploid). These haploid cells are used in the fertilization process so that the resulting fused cell will gain half their set of chromosomes from their mother and half from their father.
