Web23 de abr. de 2024 · When variations in phenotypes influence natural selection, the successful phenotype can affect the genotype distribution for the organism. For example, if organisms with a recessive gene are better adapted to the environment than those with a dominant gene, organisms with the recessive gene will become more common. WebA genotype’s fitness depends on the environment in which the organism lives. The fittest genotype during an ice age, for example, is probably not the fittest genotype once the ice age is over. Fitness is a handy concept because it lumps everything that matters to natural selection (survival, mate-finding, reproduction) into one idea. baptisia pruningWebIf 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. puhalla upmc
