Genetics of Skin Pigmentation

By Meghan Bialt-DeCelie ’19 Currently, our understanding of the genes behind skin pigmentation in humans is limited, especially for those of African heritage. Researchers led by Nicholas Crawford, PhD from the University of Pennsylvania investigated the genetic variants behind a wider range of skin colors provided from diverse African populations. Melanin is the pigment that provides the wide range of skin colors seen in the … Continue reading Genetics of Skin Pigmentation
