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 ... WebGroup selection is a process entirelyanalogous to individual selection, but acting at the level of groups.

This hostility was partly based on misunderstanding, which is now largely … WebAug 19, 2008 · Hierarchical selection subsumes genic selection—it is the more general model in that it includes genic selection as a limiting case when populations are extremely large, and gene interaction is negligible. Furthermore, hierarchical selection is productive in that it sheds light on how “individuals” of various types can evolve at levels ...

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. is matt smith a good actorWebDespite the name, the theory of genic selection considers the allele as the fundamental unit of selection. The allele is the fundamental "replicator" as it gets copied during meiosis and mitosis. Accordingly, the term replicator selection has been synonymized with genic selection.
