Description
English: Principal component analysis of genetic data of Swedish and Finnish populations. Left: A map of the studied provinces and regions of Sweden and Finland. Full population names and their sample sizes are given in the Table below. Right: Multidimensional scaling plots of genetic distances between individuals. Identity by state (IBS) distances in Northern Europe (a), Sweden and Finland (b), Sweden (c) and Norrland (d), with the legend for panels (b) and (c) in (e). The axis labels show the proportion of variance explained by the axis. In (d), the colouring of individuals represents one of the ten major river valleys of Norrland, from north to south. See also GIF file (File:3D PCA of SWE and FIN.gif) for animated three-dimensional versions of (a) and (b).
