The hair of the dog

Dogs have all kinds of hair--some short, some long, some wiry, some fluffy, some even like human hair. Geneticists have studied the DNA mutations that cause all of these differences. They found that it comes down to just three genes that make all these differences. The interesting science doesn't stop there. Scientists are using this information to understand human cancers--how just a few genes can cause so many different kinds of cancer. Read or listen to the NPR story here.
