Mexican Women’s Mitochondrial DNA Primarily Native American

In the paper, “Large scale mitochondrial sequencing in Mexican Americans suggests a reappraisal of Native American origins,” Kumar et al provide a piece of information I find extremely interesting.

“For mtDNA variation, some studies have measured Native American, European and African contributions to Mexican and Mexican American populations, revealing 85 to 90% of mtDNA lineages are of Native American origin, with the remainder having European (5-7%) or African ancestry (3-5%). Thus the observed frequency of Native American mtDNA in Mexican/Mexican Americans is higher than was expected on the basis of autosomal estimates of Native American admixture for these populations i.e. ~ 30-46%. The difference is indicative of directional mating involving preferentially immigrant men and Native American women.
