Sampling Skin Pigmentation in Africa

Caption

In a first-of-its-kind study, University of Pennsylvania researchers studied the genetics behind skin pigmentation of diverse African populations, finding new genetic variants associated with skin color. Here, senior research scientist Alessia Ranciaro measures the skin reflectance of a man from a Nilo-Saharan group. Members of this population tend to have very dark skin pigmentation.
