"Speed Gene" Identified in Thoroughbreds

Equinome, a biotech company based at University College Dublin, has identified a "speed gene" in Thoroughbred horses.  The gene may help identify the distance over which a horse is ideally suited to race.  It is the first time that a gene variant has been linked to an athletic phenotype in racehorses.
