We find that the ten most frequent haplotypes in Tlaxcala are all of Native American origin. Admixture estimates revealed that the main genetic components are Native American (75.13 $\pm$ 1.56 by ML; 69.24 based on of Native American haplotypes) and European (16.10 $\pm$ 4.98 by ML; 19.74 of European haplotypes), with a less prominent African genetic component (8.78 $\pm$ 4.09 by ML; 4.35 of African haplotypes).}}, journal = {{Human Immunology}}, volume = {81}, number = {9}, pages = {544--546}, }
