A quarter horse.
Appendix.
The horse DOES NOT have an appendix. The equivalent organ in a horse is the CECUM, which serves as a fermentation vat for fiber in the digestive tract. As in humans, the cecum is part of the large intestine. Unlike the appendix, which is an appendage that can be removed (and is necessarily removed when infected), the cecum is an essential part of the horse's digestive tract.
The thoroughbred and the quarter horse are the breeds that make up an appendix Quarter Horse.
A quarter horse is one that is registered with the American Quarter Horse Association (AQHA) or other similar registries (Australian Quarter Horse Association, for example), as having two registered quarter horse parents. The AQHA recognizes the offsrping of a quarter horse and a Thoroughbred (registered with the Jockey Club) by registering them in their "Appendix" registry. A foal born as a result of the mating of a quarter horse and a thoroughbred is referred to as an "appendix" or an "appendix quarter horse." An appendix quarter horse can attain regular registry status by earning 10 or more points in AQHA shows and races.
When you cross a quarter horse and a thoroughbred, you will get an appendix quarter horse. The paint may or may not come out in the foal. That is all in the genetics, and I would need more info to tell you that.

If registered yes, a TB/QH cross is called an Appendix Quarter Horse. They have their own association.
A Quarter horse and Thoroughbred cross is called an Appendix horse. The value of such a horse is dependant upon many factors, age, height, sex, color, breed, pedigree, show/race records, and the current local economy, and whether the horse is registered or not. There is no one set price for a horse.
Quarter Horses. But they are usually Quarter Horse x Thoroughbred crosses, not pure Quarter Horse, as Appendix QHs can be registered with the AQHA.
The Azteca is a cross between a Quarter Horse and an Andalusian.
The cross between an Arabian and Quarter Horse is not actually a breed. This cross is more commonly refered to as a Quar-ab and although the AQHA (quarter horse registry) will not accept this cross in their registry, the Arabian registry will accept this in the half Arab registry. This means you can show your horse at Arabian shows in the half Arab classes. The Quar-ab is a very pretty horse. You get the beauty of the Arabian and the calm nature of the Quarter Horse.
I actually made up this breed. It is a cross between a Thoroughbred and a Quarter Horse.
