We find that the most frequent haplotypes in the state of Nuevo León include 12 Native American and three European haplotypes. Admixture estimates revealed that the main genetic components in the state of Nuevo León are Native American (54.53 ± 0.87% by ML; 48.88% of Native American haplotypes) and European (38.67 ± 4.06% by ML; 32.59% of European haplotypes), and a less prominent African genetic component (6.80 ± 4.30% by ML; 8.26% of African haplotypes).
