1	within any population of species there will be a gene pool containing a wide variety of alleles
2	??? as the offspring also have the new advantageous allele they are in turn more likely to survive therefore over time the frequency of the new allele will increase in the population, while that of the non-advantageous ones will decrease only those individuals that reproduce successfully will pass on their alleles to the next generation however, in some cases possessing the new allele of a gene could give an individual a competitive advantage the individuals which are more likely to survive therefore have a better chance of successfully reproducing a new allele of a gene may arise from random mutation of alleles, in most cases this will be harmful these individuals will be better adapted and more likely to survive "survival of the fittest" over many generations, the number of individuals with the new advantageous allele will increase
