how does variation occur?
Asked by | 17th Feb, 2014, 04:45: PM
Variation or mutation occurs within the DNA. It is a natural result of the replication process, or the copying of one DNA strand to make new DNA during reproduction.If the new mutation ends up making some kind of variation that does not kill the organism, then the variation will be passed on to new generations.
