In the past it was believed The Recessive gene Curly Horse is any horse other than a dominant gene North American Curly Horse, that is born curly, and is resulting from two straight haired, non-curly bloodline, non-curly coated, parents. They are rare. We are referring to this particular curly coat condition as being recessive gene Curly Horses, until we have more research to direct us to a better understanding of what it is, genetically. The recessive gene Curly Horse is another breed of horse, that "crops out" curly, for some undetermined reason. It is now known that spontaneous mutations do happen in the general horse population and it could be a dominant or recessive coat gene mutation. Without isolating a curly coat gene it is unknown if it is dominant or recessive. These recessive curlies or unknown gene curlies, are definitely curly horses, with curly winter coats, and curly hair in their ears. They have occurred in the Quarter Horse, the Spanish Mustang (believed dominant gene now), the Percheron draft horse, the Arabian, the Appaloosa, the Missouri Fox Trotter, the Tennessee Walking Horse, the American Paint Horse, the Morgan, the Miniature Horse, and probably others.
ICHO does offer registration for recessive Curlies of any breed, in their R (recessive curly division). If the unknown gene acts like a dominant gene in breeding shed it will be designated U- Unknown curly coat gene. Note: ICHO/NACHR will register horses that are R/D breeding (recessive x dominant), but does not recommend the practice of mating recessive and dominant gene horses together until a test is developed to differentiate between the 2 genes. We also do not recommend mixing any unknown Curly coat genes with KRT25 or SP6. Some coat genes do not mix well and we believe it causes balding issues.
