Genetic Study Shows Diversity, Ancestry of Latino Populations, Cornell Researcher Says

Summary

---

The study includes genetic samples from 112 people from México plus 100 individuals from Ecuador, Colombia, the Dominican Republic, and Puerto Rico. The analysis shows that individuals from the Dominican Republic, Puerto Rico, and Colombia have more African ancestry, reflecting migrations along the historical slave-trade routes. In contrast, Mexicans and Ecuadorians have more Native American ancestry.

Researchers also found that the Native American segments of genomes of North American Latinos - those from México, Puerto Rico and Dominican Republic - are genetically more similar to those of the Nahua people indigenous of México and Central America, while the Native American segments of genomes of South American populations - those from Colombia and Ecuador - were most similar to those of the Quechua people.
