Meiosis produces 4 haploid cells. Mitosis produces 2 diploid cells. The old name for meiosis was reduction/ division. Meiosis I reduces the ploidy level from 2n to n (reduction) while Meiosis II divides the remaining set of chromosomes in a mitosis-like process (division).
Mitosis and meiosis differ in their end products. Mitosis results in two cells, each genetically identical to the original. Meiosis, on the other hand, results in four cells, none of which is identical to the original. Each new cell has only half as many chromosomes as did the original.
