Secondary contact and local adaptation contribute to genome-wide patterns of clinal variation in Drosophila melanogaster
Alan O. Bergland, Ray Tobler, Josefa Gonzalez, Paul Schmidt, Dmitri Petrov
The paper examines clinal variation in Drosophila melanogaster populations across North America and Australia, showing that admixture from European and African lineages contributes to parallel clinal patterns, limiting the identification of loci under local selection.
