New variation is slowly added by mutation. While some mutations may be deleterious, others can be advantageous and increase genetic variation within a population. Sexual reproduction and genetic recombination can also contribute to genetic variation, but mutations are the primary mechanism for introducing new genetic information into a population over time. The genetic composition of offspring is not always a replica of their parents due to meiosis, genetic recombination, and the potential for mutations.
