A thoroughbred/quarter horse X is called an apendix. They cannot race on the track, but there is an apendix registry. I wouldn't say that all apendixes show the good qualities of both breeds; on the contrary, I think that many show off all of the bad traits.
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.
Thoroughbred
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.

Quarter Horses. But they are usually Quarter Horse x Thoroughbred crosses, not pure Quarter Horse, as Appendix QHs can be registered with the AQHA.
A Jennet and a thoroughbred made a quarter horse!!
Thoroughbred
The obvious answer to that would be a Quarter horse.
If registered yes, a TB/QH cross is called an Appendix Quarter Horse. They have their own association.

The Thoroughbred was used in the developement of the Quarter Horse and it is still a big influence in the Quarter Horse industry today. If asked, most people know about the Thoroughbred as the world's fastest breed. But only for long distances. The Quarter Horse is faster than the Thoroughbred for short distances, such as a quarter mile race. Think of the Thoroughbred as a long distance runner as compared to a sprinter, the QH.

No Secretariat was a Thoroughbred. A much older breed that help to develop the quarter horse.
probably either a quarter horse or thoroughbred
At a quarter mile or less, the Quarter Horse. Above that distance, the Thoroughbred.
