WebNov 13, 2024 · Directional selection (a type of natural selection) is a mechanism of evolution because directional selection can result in allele frequency changes, the current definition of evolution. In population genetics, directional selection, is a mode of negative natural selection in which an extreme phenotype is favored over other phenotypes, causing the allele frequency to shift over time in the direction of that phenotype. Under directional selection, the advantageous allele increases as a consequence of differences in survival and reproduction among different phen…
