Mitosis vs. Meiosis
Cell division plays a very important role in the life cycle of a cell. Without cell division all living organisms would fail to reproduce, eventually dying out. Cell division involves two major steps: nuclear division and cytokinesis. Nuclear division is broken into two different types: mitosis and meiosis. Mitosis and meiosis are similar processes in that they both result in the separation of existing cells into new ones. They differ, however, in their specific processes …

The final variation is the joining of the gametes. The fertilization of the egg by the sperm in fortuitous. This variation doesn?t occur in mitosis because it required the exact copy to be produced.
