Following the DNA Trail

My horse, Mystic, is a mystery in many ways. I have no idea when or where he was born, exactly how old he is, and what his life was like before I first set eyes on him in 2008.

One piece of the mystery is now solved thanks to Dr. Gus Cothran, director of the Animal Genetics Laboratory at Texas A&M University.

A couple of months ago I did some internet searching on horse DNA testing. I learned about Dr. Cothran’s lab, which offers DNA genotyping for identification, parentage verification, and determination of gene mutations in animals. I e-mailed Dr. Cochran, who sent me instructions for submitting a DNA sample.

Per the instructions, I plucked about 50 hairs—including root follicles—from Mystic’s tail, taped them to a form I filled out, and sent it to the laboratory along with a check for $25.

While I waited for the results, I speculated on what they might be. A number of people thought Mystic might have some Andalusian in him. I thought there might be Quarter horse and possibly Arabian in his lineage.

But it was all guess work, since he was a paperless horse.

About two weeks after I sent Mystic’s hair samples to Texas, a white envelope arrived in the mail, with Dr. Cothran’s return address on it.

I opened it with curiosity and a little hesitation. By knowing Mystic’s heritage, I could no longer let my imagination run wild. Some of the mystery would be gone.

The results took me by surprise.

The fact that Mystic had Quarter horse in his DNA did not come as a shock. But British warmblood? Brazilian breeds? What the heck?

My research on British warmbloods yielded the following information:

The British warmblood is a mix between hot-blooded breeds (like the Arabian and thoroughbred) and cold-blooded breeds (most draft breeds). They may carry bloodlines of any approved breed, as long as they meet the requirements of the type.

Uses The British warmblood can be used in all traditional English disciplines (dressage, show jumping and eventing).
Height Average is above 16 hands high.
Conformation There are no distinct characteristics, though most horses have the typical warmblooded build.
Colors All colors are accepted, with the exception of perlino and cremello.

As for Brazilian breeds, I learned there were a number of them:

  • Brazilian sport horse
  • Campeiro
  • Campolina
  • Crioulo
  • Mangalarga Marchador
  • Pampas horse
  • Pantaneiro

I checked out each breed and decided Mangalarga Marchador looked the most like Mystic. The Marchador is the national breed of Brazil and has a royal history:

In 1807 Napoleon invaded Portugal, forcing Portugal’s Royal Family to flee to the Portuguese colony of Brazil. They took their best horses with them–Andalusians from the Royal Alter Stud Farm. One young stallion named “Sublime” went to the Baron of Aldenas, owner of the Brazilian breeding farm, Campo Alegre. The stallion was bred to local gaited mares of Spanish Jennet and Barb blood and produced offspring with a smooth rhythmic gait.

Of course, I have no way of knowing if Mystic has Marchador in him.

It’s nice to know that science still leaves a little room for imagination.

  1. Super cool stuff! And the picture of the white horse does resemble Mystic quite a bit. I had a surprise a few months ago when I found out that Sonder had Oldenburg ancestry, which was one of the breeds besides Arabian, crossed with existing native mountain and existing farm Haflingers, to bring the pure bred Haflingers back from so much loss to the two world wars. I wonder still how the Oldenburg fits and why…..could it be…let me see…..better at pulling a carriage?

    Really though, it is so, so neat to have a genetic map for Mystic. He deserves the recognition of a very worthy horse in his own rite and with his true heritage.

    I often tell the story of you and Mystic, it is still my favorite story during the time of learning together at Fiore, the summer eve when Mystic let go, and all were silent in time, and in solidarity we watched as Mystic came back to the world. I will never forget it. Thanks again for the post. E
