Scatter plot of PC1 and PC2 of GATC samples with self-reported geographic origin of all four grandparents from same continental cluster (Europe, Asia or Africa) or India. For reference, the Coriell samples are also plotted in light gray. Almost all individuals have values within or close to their expected clusters. One exception is one individual labeled as Asian with origins from Singapore that falls close to the Indian cluster (see arrow). This individual could well be a descendant from one of the many ethnic Indians in Singapore.
