Figure 1From: The genomic distribution of population substructure in four populations using 8,525 autosomal SNPsDiagram demonstrating how branch lengths are estimated for a network with three populations. Locus-specific branch lengths x, y and z, are calculated using pairwise FST distances, dAB, dBC and dAC, wher x = (dAB + dAC - dAB)/2, y = (dAB +dBC - dAC)/2, z = (dAC + dBC - dAB)/2 and A, B and C are the three populations under consideration.Back to article page
