In horse racing, a horse's pedigree can bear significant weight and influence on what kind of success he or she may or may not have on the racetrack.
Pedigree can dictate a horse's preferred surface, ideal distance and even temperament. All of these factors can combine to determine how good a horse can turn out to be. Of course, there are always horses that outrun their pedigree and exceed even beyond humble beginnings, but starting out with the deck stacked in your favor with a good pedigree never hurts.
