Figure 2. Genomic analyses.
Principal component analysis (PCA) (a) and admixture analysis (b) on
31,889 single nucleotide polymorphisms (SNPs) called for all 93
sequenced specimens. In (a) the taxonomic assignments based on
morphology are indicated with colors and circles refer to pure taxa
whereas triangles refer to hybrid species. In (b) specimens have been
ordered based on the genomic cluster analysis in (a) and color under
each bar indicate taxonomic assignments as presented in (a).
