Estimation of male gene flow from measures of nuclear and female genetic differentiation.
An approach is provided to estimate male gene flow and the ratio of male to female gene flow, given that there are estimates of diploid, nuclear gene flow and haploid, female gene flow. This approach can be applied to estimates of differentiation (F ST ) from biparentally and maternally inherited markers, assuming the equilibrium island model and equal effective numbers of males and females. Co...
متن کاملDrift and Gene Flow in Shaping Spatial Patterns of Genetic Differentiation
21 Spatial patterns of neutral genetic diversity are often investigated to infer gene flow in wild populations. 22 However, teasing apart the influence of gene flow from the effect of genetic drift is challenging given that both 23 forces are acting simultaneously on patterns of genetic differentiation. Here, we tested the relevance of a 24 distance-based metric-based on estimates of effective ...
متن کاملGenetic differentiation and estimation of gene flow from F-statistics under isolation by distance.
I reexamine the use of isolation by distance models as a basis for the estimation of demographic parameters from measures of population subdivision. To that aim, I first provide results for values of F-statistics in one-dimensional models and coalescence times in two-dimensional models, and make more precise earlier results for F-statistics in two-dimensional models and coalescence times in one...
متن کاملGenetic differentiation and gene flow among populations of the alpine butterfly, Parnassius smintheus
Levels of gene flow among populations vary both interand intraspecifically, and understanding the ecological bases of variation in levels of gene flow represents an important link between the ecological and evolutionary dynamics of populations. The effects of habitat spatial structure on gene flow have received considerable attention; however, most studies have been conducted at a single spatia...
متن کاملExtranuclear differentiation and gene flow in the finite island model.
Use of sequence information from extranuclear genomes to examine deme structure in natural populations has been hampered by lack of clear linkage between sequence relatedness and rates of mutation and migration among demes. Here, we approach this problem in two complementary ways. First, we develop a model of extranuclear genomes in a population divided into a finite number of demes. Sex-depend...
