Define how cell division and sexual reproduction help in genetic variability of the organism.

Cell division, sexual reproduction as well as genetic variability

Eukaryotic cells are able to divide by mitosis or meiosis. In humans mitosis produces new cells for growth and repair, meiosis produces sex cells (gametes) called sperm as well as eggs.

Though mutations are the ultimate source of genetic variability both meiosis as well as sexual reproduction also can contribute to new genetic combinations in offspring.
