Mitosis produces two daughter cells that are identical to the parent cell. If the parent cell is haploid (N), then the daughter cells will be haploid. If the parent cell is diploid, the daughter cells will also be diploid.  Meiosis produces daughter cells that have one half the number of chromosomes as the parent cell.

Mitosis and meiosis are similar processes in that they both result in the separation of existing cells into new ones. Telophase I of meiosis is similar to Telophase of mitosis, except that only one set of (replicated) chromosomes is in each "cell". Telophase changes are associated with the restoration of the interphase condition. In a way Telophase is the reverse of prophase. Telophase begins when the two sets of daughter chromosomes reach opposite poles of the cell. The gel of the spindle reverts to the sol state and the spindle disappears. A new nuclear membrane is formed around each set of chromosomes. The nucleoli reappear at constrictions, called the nucleolar organisers, in one pair of chromosomes. Each daughter cell gets the same complement of nucleoli at the same sites as did the parent cell.
