Kapopoulou, Adamandia; Kapun, Martin; Pieper, Bjorn; Pavlidis, Pavlos; Wilches, Ricardo; Duchen, Pablo; Stephan, Wolfgang and Laurent, Stefan (2020): Demographic analyses of a new sample of haploid genomes from a Swedish population of Drosophila melanogaster. In: Scientific Reports, Vol. 10, No. 1, 22415 [PDF, 1MB]


European and African natural populations of Drosophila melanogaster have been the focus of several studies aiming at inferring demographic and adaptive processes based on genetic variation data. However, in these analyses little attention has been given to gene flow between African and European samples. Here we present a dataset consisting of 14 fully sequenced haploid genomes sampled from a natural population from the northern species range (Umea, Sweden). We co-analyzed this new data with an African population to compare the likelihood of several competing demographic scenarios for European and African populations and show that gene flow improves the fit of demographic models to data.
