Moderate hypoxia influence at intermediate altitude in Argentinean Andes

This study evaluates genetic and phenotypic variation in the intermediate altitude Calchaquí population living in the Calchaquí Valleys of the Argentinean Andes in the town of Cachi at 2300 m. This study attempts to pinpoint evolutionary mechanisms underlying adaptation to moderate hypoxia at a intermediate altitude. DNA from 24 saliva samples of Calchaquíes living at 2300 m in Cachi in the Province of Salta in Argentina was genotyped.
