Plot of first (PC1) and second (PC2) principal component scores for each individual in the sample, indexed to the reference populations (GOAL and MEX samples).

Includes Mexican (Mex), Colombian (Col), Honduran (Hon), Cuban (Cub), Puerto Rican (Pur), Haitian (Hai), Dominican (Dom), Central European (CEU), Yoruba African (YRI), and Native American (NativeAm) populations. Individuals from the present study are labeled “Miami”
