Do all impressive horses have HYPP?
In 1992, researchers designated the Impressive line of horses as carriers. Not all horses of that line had HYPP, but all horses with HYPP were descended from Impressive himself. In 1994, a genetic test that utilized DNA from hair or blood, was perfected, this determined whether a horse had HYPP or not.
