Research implicates gene mutation in ancient dog's hairlessness
Mexican hairless dogs are an ancient breed. For millennia, they have kept the secret of their bald beauty, even from the Aztecs who revered them. Now, an international team of researchers led by Tosso Leeb, a geneticist at the University of Bern in Switzerland, has discovered a mutation in a previously uncharacterized gene. This mutation, the team reports, makes Mexican hairless, Peruvian hairless and Chinese crested dog breeds bald, or partially bald.
