Originator of the contemporary Dosage system, Steve Roman, Ph.D., has written the definitive book on the subject. Although originally devised as a breeding theory, Dosage has evolved into a pedigree classification technique used by owners, breeders and handicappers to buy, breed and bet on the best. Roman's research and development of the roster of chefs-de-race, those prepotent sires that have shaped the breed, has changed the way Thoroughbreds are bred, bought and sold.
