Figure 5From: Human genetic differentiation across the Strait of GibraltarSchematic representation of the two grids of demes representing South-Western Europe (SWE) and North-Western Africa (NWA). The whole simulated area is subdivided into 256 demes. The two crosses represent the demes where the settlement of the areas starts from a common genetic pool t generations ago. There are two different migration rates: m intra is the migration rate between demes within a continent (either SWE or NWA) and m inter is the migration rate between demes among continents. Continents are connected by 8 demes on each side.Back to article page
