Meiosis and mitosis differ from each other. One is the procedure on preparing sex cells and the other is for forming new cells. Meiosis is used for establishing sex cells. Once the operation is ended, you will have four sex cells. Mitosis, however, is just for forming new cells. Once this exercise is complete, you will only get two identical cells. In other words Meiosis involves two divisions of the nucleus, while mitosis involves only one. Meiosis produces four sex cells that are haploid, meaning they have half the number of chromosomes. Mitosis, on the other hand, produces two cells that are identical to the original cell. These cells are diploid, meaning they have pairs of chromosomes.
