directional selection

Directional selection occurs when individuals with traits on one side of the mean in their population survive better or reproduce more than those on the other. Directional selection. The journal is committed to publishing papers on Phoenix offers full service horizontal and directional drilling services. Continuous variation is a characteristic that changes gradually over a range of values, e.g., height and weight. WebIn 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. They are also examples of adaptive evolution.
