	A fish of a different color - February 2006 The zebrafish, a small but flashy aquarium pet, may seem like an unlikely informant on questions of human genetics — yet its genome could hold the keys to understanding many diseases and, surprisingly, the genes underlying human skin color. In December 2005, a cancer research team headed by Keith Cheng at Penn State University announced that their studies of the mutant "golden" zebrafish had taken an unexpected turn: they had discovered a single human gene that accounts for about 30% of the difference in skin color between African and European descendents...
