EAS, SAS, EUR, AMR and AFR: East Asian, South Asian, European, Admixed American, and African, respectively. (A) Principal components analysis (PCA) of the 2504 individuals using ~300,000 SNPs. (B) PCA on genotype fingerprints (N = 2504) with L = 5000. (C) PCA on genotype fingerprints of European populations (N = 503) with L = 5000. (D) PCA on genotype fingerprints (N = 2504) with L = 500.
