Mitosis: Mitosis is a type of cell division that results in daughter cells that are genetically identical to the parent cell. Mitosis occurs in the somatic cells of the body. Somatic cells include all of the cells of an organism except for egg and sperm cells.
Meiosis: Meiosis is a type of cell division that results in daughter cells with half the number of chromosomes as the parent cells. Meiosis also involves a process called crossing over which results in genetic material being rearranged between homologous chromosomes. Meiosis occurs in the germ cells of the body. The germ cells are the egg and sperm cells.
If an organism has 15 pairs of chromosomes, it has a total of 30 chromosomes. At the end of the telophase step of mitosis, the daughter cells will have 30 chromosomes and will be genetically identical to the parent cell.
At the end of the telophase II step of meiosis, the two cells will each still have 30 chromosomes. After cytokinesis during meiosis, which happens right after telophase II, the four daughter cells will each have 15 chromosomes.
