WebApr 8, 2024 · The genetic architecture of phenotypic traits can affect the mode and tempo of trait evolution. Human-altered environments can impose strong natural selection, where successful evolutionary adaptation requires swift and large phenotypic shifts. In these scenarios, theory predicts the influence of few adaptive variants of large effect, but … WebThe figure looks at the three modes of selection in a mouse population with a range of fur color phenotypes. Different modes of selection are seen under different sets of environmental conditions, and each mode has a different effect on the population.
