Identification of Mitochondrial Haplogroups in Native Mexican and Mestizo Populations

Summary

This is an abstract from the "Ancient DNA in Service of Archaeology" session, at the 84th annual meeting of the Society for American Archaeology.

Currently in Mexico there are around 68 ethnic groups, grouped into 11 linguistic families, representing 15% of the Mexican population. The mitogenome (mtDNA) has allowed us to make inferences about the history of and relationships between these populations. However, the evaluation of the mitochondrial genetic structure in the Mexican population has been restricted to a small proportion of the underlying ethnic diversity among these populations. The complete sequencing of the mitogenome has generated specific information of the populations and has increased our understanding of the population events that have shaped the population structure of today. The present study focused on the characterization of the variants and haplogroups that represent the Mexican population across the country, taking samples from each state. We identified the four previously reported Native American haplogroups A2 (55%), B2 (23%), C1 (18%), and D1 (4%), and 73 subhaplogroups, most of them not previously reported in the Mexican population. Some haplogroups suggest association with metabolic diseases. It is concluded that within the indigenous populations there is great genetic diversity, providing clues about the history of the population, including its origin, divergence, and migrations, thus contributing to the knowledge and understanding of the settlement of the Americas.
