Canine eugenics

"In Age of DNA, the Dog Becomes a Guinea Pig"

Interesting excerpt:

A mutation similar to the one that makes some whippets faster also exists in humans: a sliver of genetic code that regulates muscle development, is missing.

“It would be extremely interesting to do tests on the track finalists at the Olympics,” said Elaine Ostrander, the scientist at the National Institutes of Health who discovered that the fastest whippets had a single defective copy of the myostatin gene, while “bullies” had two.

“But we wouldn’t know what to do with the information,” Ms. Ostrander said. “Are we going to segregate the athletes who have the mutation to run separately?” For the moment, it is whippet owners who find themselves on the edge of that particular bioethical frontier.
