<!--QuoteBegin-->QUOTE<!--QuoteEBegin-->Much of the genetic mechanism remains to be unraveled but one conclusion is pertinent to this essay. Several independent genes must work in concert to produce the deepest complexion—the extreme of the darkness adaptation. Many things can go wrong and, when they do, the result is a lighter complexion. For instance, deleterious mutations at the five loci above result in various forms of albinism, whether the patient’s heritage is dark or pale. In other words, there are many random ways “accidentally” to evolve a light complexion. <b>But no genetic defect can make the child of light-skinned parents come out dark.</b>
