Principal components analysis of genotype probabilities for bluehead, flannel-mouth, white, longnose, and mountain suckers and their hybrids. Each point represents one individual fish, labeled according to phenotypic identification. Parental species are shown as solid points. Hybrid individuals are shown as crosses, and are abbreviated in the legend (e.g., “F × W” is a flannelmouth×white hybrid). Each principal component separates out a species based on individual-level genetic variation at 4,095 SNPs. A) PC1 separates bluehead suckers from flannelmouth and white suckers, while PC2 separates flannelmouth from white suckers. B) PC3 distinguishes longnose suckers from the other species. C) PC4 separates mountain suckers from the other species.
