    This is allopatric speciation. This is an example of stabilizing selection in a population because the organisms in the middle of the population have the best fitness for their environment. The five conditions impacting this equilibrium are: mutations, nonrandom mating, genetic drift, migration, and natural selection. Natural selection impacts single-gene traits because of the possible extinction of one trait or increase of another trait. If a trait is found to be not preferable in that environment, it could be eliminated through natural selection. The total allele frequency in the Hardy-Weinberg equilibrium has to equal 1.
