Mexican genomes show wide diversity
After five years, scientists have mapped the genomes of 300 mestizos, people of mixed Indian and European background, in Mexico. The findings include significant differences between mestizo genetic makeup and those of people with European and Asian ancestry.
Better genetic maps potentially help doctors tailor medicine to the individual. It will be easier to identify genetic risk markers, develop treatments, and prevent diseases including diabetes, hypertension and obesity.
Among the individuals studied, those from northern states were genetically closer to Europeans, while those in southern areas were genetically closer to Native Americans.
