Figure 3
Neighbour-joining tree using Nei’s genetic distance for Galician populations. Bootstrap values (%) are shown on the trees. The RB (circles) and SU (squares) ecotypes group by shore (Corrubedo, green; Silleiro, blue; Cetarea, red) when nonoutlier loci are used, but by ecotype and then shore when outlier loci are used (redrawn from Galindo et al. [20]).
