““I need not point out that being redheaded is not a maladaptive condition. It’s a very lovely condition. It is an absurdity, offensive to both redheads and geneticists—a group that contains both family and friends—to suggest that red hair might be subject to a force of natural selection so powerful that oblivion awaits. Even actually maladaptive genetic traits, actual diseases with well-understood modes of inheritance, such as cystic fibrosis or Duchenne muscular dystrophy are not likely to go extinct, because carriers of a single copy live healthily and pass the faulty gene on to their children.””
