Re: Isolated populations

Very cool theory Bev! That just might explain it! Why else would a North American Spanish horse group be closely related to horses that are not even in the same are? You would think that the Sulphurs would relate closely to those found in the south west, but instead, they have South American genetics!

A sneaky way to get South American genes into North American Spanish horses when you think about it! lol

Does anyone know who the Cerbat horses closely relate to?

Re: Isolated populations

I am so sorry I deleted my origanal post cause I didn't want to keep hard feelings going.

What I said was Pizzaro brought horses from Spain to Mexico in 1502...and then HE steadily moved southwards. The horses in Chile came from his horses in Peru.

This study shows relationship but its not easy to me anyway.

Re: Isolated populations

I love the information you dig up Bev!

What would be a very interesting work is to explain the historical, genetic, and conformational differences of all of the US CS horse breeds. I would also be curious as to how closely they relate to the South and Central American CS horse breeds. We know that the Sulphur is a Central and South American horse genetically (Paso Fino and Chilean Criollo is their closest relatives genetically), I wonder which other North American Colonial Spanish horse breeds relate to the Colonial Spanish horse breeds of Central and South America?

Re: Isolated populations

The Bankers is part of some of the reading I have been doing on them:

"Historical research and genetics testing indicates that these wild horses(Bankers) descended from a core group of the old type of Spanish horses. One genetic factor, the blood variant Q-ac, is believed to be contributed by the Spanish horses of 400 years ago. This genetic marker has been found in only descendents of those Spanish horses. Easily lost through genetic drift, Q-ac has been documented in the Puerto Rican Paso Finos, the isolated mustang population of Montana's Pryor Mountains, and the horses of Shackleford Banks."

The Bankers are a treasure and my future with these horses is leaning towards them. The more I read about them, the more fascinated I am.

Re: Isolated populations

The Sulphur's also have the Q-ac variant.

Thanks for the contribution Christi! Does anyone have the genetic report to read on the Bankers??

Re: Isolated populations

OK I can't speak about the Pryor Mt. Horses...but I do the Narragansett Pacer played a big role in the formation of the Puerto Rican Paso.

Want to talk about a mystery there....where did the Narragansett Pacers come from. I know they have Andalusian blood in them because I know the name of the man who introduced it into the herd.

Re: Isolated populations

Bev, I have never heard of that before. Where did you read about that?

Re: Isolated populations

There are many articles on the Narragansett Pacer. I was reading one last night that made them out to be Irish Hobbies. They were imported by Robertson...which works for me. An Andalusian was introduced to make the breed fancier.

And it was exportations that doomed the breed to extinction. The Carribean and South America were big purchases.
