With the start of the 2010 Winter Olympics just a week away, we'll talk about an emerging potential threat to fair competition -- gene doping. How will advances in genetic manipulation affect athletics, and are athletes and referees prepared? We'll talk with Theodore Friedmann, chair of the World Anti-Doping Agency's Gene Doping Expert Group, about the issue. Should sports officials begin making genetic tests part of their toolkits, alongside tests for performance-enhancing drugs and steroids?
