Chev - anything about breeding you dont know?

I took my information about the Tiger horses from their register which is.... let me find it....
www.tigrehorse.com
where it states;
'We understand that an extinct horse can never be revived but because genes from the ancient "Heavenly" or Tigre horses were saved by others who out crossed to local breeds, a variety of international breeds now show a relationship to those earliest horses. The American Appaloosa horse is just one of them. From certain types of horse, we at TIGRE in the USA have reached into the Appaloosa breed and extracted desirable color genes for our modern day Tiger Horse breed. We also carefully selected for a certain body type. These we crossed on solid colored gaited breeds that displayed similar look-alike characteristics to each other, and the first Tiger Horse was born. First, second, third and even fourth generation Tigers are now available for sale or breeding.'
And also;
'Fortunately for TIGRE The Tiger Horse Breed Registry and the Tiger Horse members and breeders, genes take millions of years to disappear or even change. The founders dream was to extract the Lp gene (otherwise known as leopard spotting gene or "Appaloosa"coat patterns), and put it into gaited horses. The dream to create a superior American version of this once famous horse known to have roamed the Steppe, is now a reality.'
Hence my belief that they are mostly appaloosa's crossed with any other horse that they wanted for the breed characteristics (whether those be gaited horses or others that they saw a desirable trait in).
And the Nez Perce information I got from... (this may take longer to find)...
(just a side note - isnt the History button useful?

... sadly not useful enough though, Im going to have to re-do my search...)

Admittedly this is a breeder.
'OUR MISSION:
The Nez Perce people are historically known for their selective horse breeding practices, especially of the Appaloosa horse (“Maamin,” the Nez Perce word for Appaloosa). We strive to follow the lead of our ancestors and carry on their legacy and traditions by breeding, training, riding and trading (selling) Appaloosa stock - - for our own enjoyment and that of our family, our community and our friends (old and new).
When we started our breeding program, we had Appaloosas (Appys) with STRONG Foundation lines. We strengthened our Appy bloodlines even more when we obtained some nice, "old herd" Appy mares from the Minam line in Wallowa, Oregon. (See our Breeding Section.)
In 1995, to support our Nez Perce Tribe’s new Nez Perce Horse Registry, we bred some of our Appy mares to the Tribe's Akhal-Teke stallions (see our Breeding Section). We now have Appy and Akhal-Teke mares that we breed to our Appy and Akhal-Teke stud. We are very pleased with the Appearance, Temperament, Athleticism and Performance of this cross!
However, the large herd of the M-Y Sweetwater Appaloosa Ranch is still predominantly Appy, and we’ll continue our efforts to preserve the wonderful Appaloosa horse!'
Does that then mean that the Nez Perce is in fact a variant of the appaloosa, like the Welsh sections? If this is the case, why is it a seperate breed rather than just a section? (is it even a seperate breed? This site is reluctant to tell me).
So I appreciate your concern, but I did read before I posted.

. The site for the Nez Perce wasnt clear and on second reading it seems only selected breeders add Akhal Tekes to their appaloosa stock.
And as for becoming a pro-active learner - isnt that what this board is here for?
