Figure 6

Genetic relationships among the 10 three-spined stickleback populations from the Baltic Sea. (a) Principal coordinates analysis (PCoA) plot of the overall average pairwise F ST values of the subset of 9,404 SNPs among the 10 three-spined stickleback populations. (b) Neighbor-joining tree of the same populations based on F ST values of each of the subset of 9,404 SNPs. Numbers on tree nodes represent bootstrap values of 1,000 replicates. Populations from different geographic regions are marked in color: red, North Sea; green, southern Baltic Sea; yellow, Gulf of Finland; blue, Gulf of Bothnia and Baltic proper.
