Mitosis vs. Meiosis

Mitosis produces cells that are identical to the parent cell Mitosis produces cells that are identical to the parent cell. Mitosis occurs in all somatic cells, not egg or sperm. Somatic cell → 2n 2n 2n Meiosis produces cells that are genetically different to the parent cell. Meiosis produces gamete cells. n 2n n n n
