What causes genetic variation in a population?

Answer:
Meiosis. Mitosis is asexual. Meiosis creates genetic recombination through sexual reproduction. This provides different genes (chromosomes) to be combined and create different organisms. Mitosis makes the offspring the exact same as the parent because the same set of genes (chromosomes) are used in the creation of the cell.
