Genetic distance from individuals in the IIPGA data to the three continentally defined HapMap groups. Individuals cluster according to ancestral continent of origin but the clusters are less compact than those seen with the Perlegen data because of the smaller number of SNPs. Individuals intermediate between clusters, like those labeled with arrows, may have a high degree of admixture.
