Fig. 2From: Recently integrated Alu insertions in the squirrel monkey (Saimiri) lineage and application for population analysesPopulation Structure analysis based on 110 Alu insertion polymorphisms and 32 squirrel monkey individuals for K = 2. The percent assignment of each individual to K = 2 clusters is shown on the Y-axis. The ID numbers and species names are shown on the X-axis. K = 2 captures the population structure of the two Saimiri groups, S. sciureus and S. boliviensis, and is consistent with the geographic origins of these samplesBack to article page
