Caption: University of Utah biologist K. Gordon Lark holds his dog, Mopsa, a Portuguese water dog with wavy hair. President Obama's dog Bo is a Portuguese water dog with curly hair. Lark was part of a team, led by National Institutes of Health geneticists, that showed variations in three genes account for seven major kinds of dog coats. Lark and colleague Kevin Chase helped find the gene responsible for curly hair or wavy hair.
