Genic selection
Webquantified. As meiotic drive is equivalent to genic selection on evolu-tionary time scales (10), we may summarize its strength in terms of an effective selection coefficient, s, acting against PRDM9 binding al-leles. This selection must be strong enough to explain the substantial divergence between humans and closely related species at PRDM9 Webgenic selection A form of selection in which the single gene is the unit of selection, such that the outcome is determined by fitness values assigned to different alleles.

Curves correspond to the ... WebFeb 7, 2024 · The answer is 'no'. But a dialectical strategy employed by Williams (1966) has created the converse impression. Williams argued that selection at higher levels is intrinsically weaker than selection at lower levels, so should only be invoked if absolutely necessary; he also argued that 'genic selection' can explain all known adaptations.

WebJan 30, 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. We measured the effects of inbreeding on an intrasexually selected color signal ...
WebThere is a further complication with respect to the nature of the genic selection models put forward by genic pluralists. These models function under the presupposition that they are at least mathematically equivalent to hierarchical models. This claim has largely depended on the work of Dugatkin and Reeve in establishing this equivalence ... highway shoulder crosswordWebThe theory of kin selection helped resolve many questions dealing with the evolution of social behavior, and was shown to give a robust prediction of sex ratios in hymenopteran (ant, bee, and wasp) colonies. From the above inequality, it was argued that kin selection (for altruism in family groups) was reducible to individual or genic selection. highway shoulder barrierWebAbstract.
