No. Genetics is a topic in biology. I think what you mean is, the mutations that form in DNA to give different features may be beneficial to the survival of the organism. E.g. Giraffes with long necks are more likely to survive than the giraffes with short necks because they can reach leaves on higher trees but the short giraffes can not. The short giraffes have evidently become extinct as a result.
