Gene Frequency and Evolution
... Evolution will dictate a change in gene frequencies. When a variation, caused by either recombination or mutation, occurs in an organism, it may provide a survival advantage. That advantage usually results in a structural or behavioral change that will help an organism compete for resources better. ...
