Figure 4From: Single nucleotide polymorphism discovery in cutthroat trout subspecies using genome reduction, barcoding, and 454 pyro-sequencingPrincipal coordinates analysis plot. Results of PCoA showing the first two principal coordinates that, combined, explain 51.5% of the observed genetic variation. Shapes on the figure legend correspond to the a priori subspecies designations. Subspecies are abbreviated the same as in Figures 1 and 3. Colors correspond to the population assignments made by Structure analyses (see Figures 5 and 6).Back to article page
