Fine-STRUCTURE hierarchical clustering dendrogram based on haplotype sharing patterns observed among the considered Native Mexican groups and their geographical locations. Population clusters were defined by considering branches of the dendrogram that split with a posterior probability above 90%. Accordingly, the Northern Mexican Cluster included SER and TAR populations, the Central Mexican Cluster was made up of groups from Central West and Central East Mexico (i.e., HUI, NAH, NAJ, NAP, and PUR), while the Southern Mexican Cluster grouped populations from Southern Mexico (i.e., TRQ, MAZ, ZAP), South East Mexico (i.e., TOJ, TZT, LAC, MYA), and Central East Mexico (i.e., TOT). The dotted line in the geographical maps indicates the demarcation between Aridoamerican (northward) and Mesoamerican (southward) regions, which represent the main geographical and cultural areas of ancient Mexico and whose population clusters showed the greatest genetic differentiation according to Fst analyses. The geographical maps have been plotted using the R software (v.4.0.2).
