Webdirectional selection on male ornaments, as well as subsequent indirect selection on the preference itself. Changes in the frequency distribution of mating preference functions may also lead to shifts in the net direction of selection and, in some cases, disruptive selection may even occur, leading to speciation (Turner & Burrows, 1995). In ... Web30 de ene. de 2024 · Thus, there may be strong directional selection on these traits, toward enhanced signal quality. This renders sexually selected traits particularly susceptible to inbreeding depression, due to relatively low ratios of additive genetic variance to dominance variance.
