Architecture of Parallel Adaptation in Ten Lacustrine Threespine Stickleback Populations from the White Sea Area
Abstract Adaptation of threespine stickleback to freshwater involves parallel recruitment of freshwater alleles in clusters of closely linked sites, or divergence islands (DIs). However, it remains unclear to what extent the DIs and the alleles that constitute them coincide between populations that...
