In many breeds -- Arabians, Morgans, Quarter Horses -- the "old style" horses cannot possibly win in the show ring, and yet...these horses remain an invaluable genetic resource for their breed. Whenever not-so-smart breeders go astray down blind alleys of style that are detrimental to the breed, these "old style" horses provide a genetic way out. Crossed with the current style animals that have remained sound and healthy, the old style horses can provide needed genetic diversity while at the same time restoring those qualities that made the breed so desirable in the first place. It might well be a wise choice to breed back to one of these animals every few generations so as not to lose essential traits. In both dogs and horses, the cross of a sturdy, plain, but structurally correct mare on a more extreme, typey stud has produced some exceptionally good animals that benefited their breed.
