Natural selection occurs when there are differences in fitness among members of a population. As a result, some individuals pass more genes to the next generation. This causesallele frequencies to change. WebIf the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change). Mechanisms of evolution correspond to violations of different Hardy-Weinberg assumptions. They are: mutation, non-random mating, gene flow, finite population size (genetic drift), and natural selection. condo for sale east ave rochester ny
