Evaluating Loci for Use in the Genetic Analysis of Population Structure
TL;DR: It is suggested that genetic variation at a discrepant locus, Identified under these conditions, is likely to have been influenced by natural selection, either acting on the locus itself or at a closely linked locus.

TL;DR: A perspective on the context and evolutionary significance of hybridization during speciation is offered, highlighting issues of current interest and debate and suggesting that the Dobzhansky–Muller model of hybrid incompatibilities requires a broader interpretation.
Journal ArticleDOI
Spatial patterns of genetic variation generated by different forms of dispersal during range expansion
TL;DR: It is shown how the three forms of dispersal during colonization bring about contrasting population genetic structures and how this affects estimates of gene flow.
Journal ArticleDOI
Gene trees and species trees are not the same
TL;DR: The relationship between species is usually represented as a bifurcating tree with the branching points representing speciation events, but a different picture is emerging from new empirical evidence, particularly that based on multiple loci or on surveys with a wide geographical scope.
Journal ArticleDOI
A method for quantifying differentiation between populations at multi-allelic loci and its implications for investigating identity and paternity
TL;DR: A method is proposed for allowing for the effects of population differentiation, and other factors, in forensic inference based on DNA profiles, which is currently used in some UK courts and has important advantages over the ‘Ceiling Principle’ method, which has been criticized on a number of grounds.
