The Curly horses genetic
Scientific reflections are justified on this race very separately. The Curly is a horse with curly hair (to different degrees) and so-called hypoallergenic.
The gene responsible for the curly hair has been found in a recessive form in other breeds (Quarter - Percheron - Arab - Appaloosa - Missoury Fox trotters, ...) without however bringing the hypoallergenic asset.
US scientists have begun further research to find out why these curly horses have fewer allergens than other horses, which is a boon for many allergic riders.
