Researchers find that the higher a person’s proportion of African ancestry, the more likely that person reported having curly hair, high blood pressure and type 2 diabetes, and the less likely that person reported having facial wrinkles, rosacea and Parkinson’s Disease

Also the higher a person’s proportion of European ancestry, the greater the chance that person carries variants that are more common among Europeans than among Africans, such as those linked to HIV-resistance and alpha-1 antitrypsin deficiency.
