F(ST) and Q(ST) under neutrality.
A commonly used test for natural selection has been to compare population differentiation for neutral molecular loci estimated by F(ST) and for the additive genetic component of quantitative traits estimated by Q(ST). Past analytical and empirical studies have led to the conclusion that when averaged over replicate evolutionary histories, Q(ST) = F(ST) under neutrality. We used analytical and s...
متن کاملLetter to the Editor Under Neutrality , Q ST # F ST When There Is Dominance in an Island Model
TO test whether quantitative traits are under directional or homogenizing selection, it is common practice to compare population differentiation estimates at molecular markers (FST) (Wright 1951) and quantitative traits (QST) (Spitze 1993). If the trait is neutral and its determinism additive, then theory predicts that QST 1⁄4 FST, while QST . FST is predicted under directional selection for di...
متن کاملScaling biodiversity under neutrality
Introduction To better understand biodiversity scaling, it may be useful to characterize the biodiversity scaling relationships that arise from the neutral perspective. This exercise will help in formulating quantitative null hypotheses for observed biodiversity scaling relationships. Here we use the term biodiversity to refer not only to species richness, but also to relative species abundance...
متن کاملCoalescents and genealogical structure under neutrality.
Genealogical or coalescent methods have proved very useful in interpreting and understanding a wide range of population genetic data. Our aim is to illustrate some of the central ideas behind this approach. The primary focus is genealogy in neutral genetic models, for which the effects of demography can be separated from those of mutation. We describe the coalescent for panmictic populations of...
متن کاملMultivariate QST-FST comparisons: a neutrality test for the evolution of the g matrix in structured populations.
Neutrality tests in quantitative genetics provide a statistical framework for the detection of selection on polygenic traits in wild populations. However, the existing method based on comparisons of divergence at neutral markers and quantitative traits (Q(st)-F(st)) suffers from several limitations that hinder a clear interpretation of the results with typical empirical designs. In this article...
