Argentine polo turns to genetic mapping to trot out champions

BUENOS AIRES - Are champions born, or raised? That's the question scientists in Argentina are trying to answer as they look to pinpoint the genes that make local horses the best in the world for playing polo.

In Argentina, polo is a big deal, and big business, and to that end, cloning has already been used to reproduce the finest existing mounts.

But scientists want to go one step further and map the entire genome of the Argentine polo horse in order to create the perfect specimen.
