Structure analysis of Bolivians and Totonacs using a panel of 324 AIMs. a) New World ancestry is predicted for all Bolivians and Totonacs. A non-New World ancestry component is correctly distinguished in the ten Bolivians with European admixture. b) A subset of 173 AIMs present in the merged genome-wide data set (this study,  and ) identifies New World ancestry in other unrelated Native American populations and demonstrates transferability to other New World populations that were not used to ascertain the AIMs. c) 47 AIMs from Kosoy et al. present in the merged data.
