Many studies have suggested that the genetics of skin pigmentation are simple. A small number of known genes, it is thought, account for nearly 50 percent of pigment variation. However, these studies rely on datasets consisting ...

People with light skin tones are far more likely to develop melanoma skin cancer than people with dark skin tones. This large disparity results from far more than can be explained by the UV protective effects of melanin pigment, ...
