Figure 3 Clustered fineRADStructure coancestry matrix based on 8,049 PE-ddRAD loci. Pairwise coancestry coefficients are colour coded from low (yellow) to high (black). Every name represents a discernible discrete cluster based on the pairwise matrix of coancestry coefficients, defined by a posterior probability > 0.9 in the finestructure tree. Note that the three major clusters represent the three genera and that most species and subspecies included in the study are recovered as unique clusters.
