14. Mutation . (back ) A rare change in the DNA of genes that ultimately creates genetic diversity (Campbell, 1996). 2. Random mating . Gene flow . (back ) Movement of genes from one population to another via sexual reproduction between members of the populations. 7. Genetic drift . (back ) Changes in the gene pool of a small population due to chance. 15. Natural selection . (back ) Differential success in the reproduction of different phenotypes resulting from the interaction of organisms with their environment. Evolution occurs when natural selection causes changes in relative frequencies of alleles in the gene pool. Since few, if any, of these conditions exist in real populations evolution is continually occurring. Mutations do occur (albeit rarely), mating is often not random, gene flow is frequent in small populations (migration), genetic drift is probable, and natural selection is a continuous phenomenon in nature. Allelic frequencies
