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).
