DNA determines the body design of an individual. The DNA that gets transferred from parents to offsprings makes them look similar. DNA copying is important for reproduction. Additional copies of DNA are made during replication which is necessary for the new cells formed after cell division.

The variations ensure that the survival of the species as they allow the members of population to adapt to the changing environment and conditions. The species are more suitable to the changed environment . Thus continuity of the species is maintained.

If a trait A exists in 10% of a population of an asexually reproducing species and a trait B exists in 60% of the same population, trait B is likely to have arisen earlier because this trait has been replicating and existing in a higher percentage of the population as compared to trait A.

The variations ensure that the survival of the species as they allow the members of population to adapt to the changing environment and conditions. The species are more suitable to the changed environment . Thus continuity of the species is maintained.
