<span>When an error occurs in dna duplicating itself it might be produce a beneficial mutation. This genetic variation might in itself be good because it gives it a better chance to survive in its natural environment. If this continues it will be more carried in general population because it increases the entity's ability to survive.</span>
<span>Because of semi-conservative replication in DNA synthesis, One of the strands of the new DNA molecule is original and one of the strands of the molecule is composed of new nucleic acids.</span>
I believe the correct answer would be <span>variation. The definition of variation in biology means,</span><span> any difference
between cells, individual organisms, or groups of organisms of any
species caused either by genetic differences or by the effect of environmental factors on the expression of the genetic potentials. So i think that organisms can also be classified as variation. Hope this helped. ♥ ☺
