>>>> No they don't. The QH has become specialized for several different disciplines. You will not find Paint blood in a QH bred for reining, cutting, ranch, racing, hus, dressage, halter or pleasure.
You are right that you won't find too many registered Paints in most QH pedigrees, because up until recently, AQHA wouldn't register the excessive white offspring of QH x QH so, necessarily, those horses had just APHA papers.
HOWEVER, if you take the TOP horses bred for reining, cutting, hus, halter, or WP in both AQHA and APHA and compare their bloodlines, you will more often see similar than dissimiar lines. >>>>> Anybody breeding QH's or Paints for the serious QH or Paint markets, don't cross the breeds.

So there are definitely some people breeding for the serious Paint market that DO use QH close up and often-- the same lines that are winning in comparable disciplines at AQHA shows. >>>>> And any horse with one or the other breed more than three generations back no longer counts as a 'crossbred' because there isn't enough genetic material to worry about.
APHA accepts using a QH or TB parent for a fully registered Paint, so for APHA, Paints with QH or TB blood are not considered crossbreds regardless of where in the pedigree those other breeds fall. I wasn't calling Paints with QH parentage crossbred. They are fully registered Paints according to APHA. >>>>>If we are to believe what you're saying, then the TB and the Arab, and a whole other list of breeds are essentially the same because they came from the same bloodlines...but clearly they are breeds unto themselves.
The closing of the books for the Arabian breed pre-dated the formation of the TB, so moot point. The TB allowed crossing to Arabian into the 20th century, but their books have been closed to that option for at least 70 years now (and the cross was not being used for many years prior to its "official" removal). APHA, on the other hand, still allows crossing to QH with no limits as to amount or frequency of its use.
And I never said that I do not consider APHA and AQHA to be seperate breeds-- only that I consider them similar breeds with similar bloodlines and similar traits, overall. >>>>> The horse in my avatar is by a roping bred Paint stallion...not one registered QH within the first 5 generations.
Link to pedigree, please? I would like to see how he is bred.
I am not saying that APHA x APHA breeding does not occur, sometimes for generations, and that certain lines have less recent QH influx-- I am saying that IMO because of their common roots and because of the continued allowance of QH blood, and the common use of it, my opinion is that the breeds, ON THE WHOLE, are more similar than they are different--
And, in keeping with this thread, in both QHs and Paints (as overall breeds) IMO there is comparable potential for finding temperaments suitable for a beginner.
