Web30 de set. de 2010 · Background In any natural population, mutation is the primary source of genetic variation required for evolutionary novelty and adaptation. Nevertheless, most mutations, especially those with phenotypic effects, are harmful and are consequently removed by natural selection. For this reason, under natural selection, an organism will … Web27 de abr. de 2024 · Cox EC, Gibson TC. Selection for high mutation rates in chemostats. Genetics. 1974;77: 169–184. pmid:4603159 .
