Unsupervised hierarchical clustering of the 877 individuals from the 37 populations. Results for k (number of clusters) = 3, k = 5, k = 7, k = 10 and k = 37 are shown. Individuals are grouped by population. Each individual is represented by a vertical bar. The proportion of the bar in each of k colors corresponds to the average posterior likelihood that the individual is assigned to the cluster indicated by that color. Populations are separated by black lines
