My Mustang DNA results - thoughts?

I got the DNA results back on my BLM Mustang (I used the Texas A&M lab), and the results are not what I would have guessed. The 3 prominent breeds they cited are small in stature and includes Welsh Pony. Hercules is 17.2hh!

I thought about having another test done somewhere else but Kentucky and UC Davis say their DNA tests cannot reveal the breed. So I was curious, how vague or accurate is a DNA test for breed identification?

Here are the results:

Here is how he looks next to an average 15hh Quarter Horse:

How much did it cost? I ask because I know 100% what breed mix my Aires is and if it isn't too expensive, I'd do it to provide a baseline for questions like this.

As it is, I have a hard time believing that breed mix for a mustang. Especially the akhal teke.

I've been wanting to do the same thing with my horse :)

These tests are nuts. We did one for our dog, 16 pound little thing. Mother was a pure chihuahua, we met her, still nursing the litter.

We then met the dad, a min pin.

The test showed chowchow on mother's side.
Then for the dad, giant schnauzer, black lab and a couple others I don't recall. All big ol dogs!

My guess was chi x schipperke. Which, most people looking at her and a picture of schipperke, or other dogs, would agree to.

My point would be that these tests can be wildly inaccurate. I wonder what factors they are using to call it one breed or another. Maybe they use the same ones for some breeds and things get mixed up. Who knows.

they state its more breed type than preed. Alhal Teke is more of eastern horses of Non arabian blood. the welsh could be from another closely related breed (so any smaller european horse). i want to get my arabian tested to see what it says. though UC DAvis its $75 i think. the horse one is a bit more accurate than the dog one. the dog one is a mess as most purebreds are even closely related to other breeds.

Well, that's the thing. There's really no such thing as a "pure" breed of anything, because all of the recognized breeds were created by mixing animals of different types, some known and some unknown. That's why they don't endorse using the tests on "purebred" animals, because results will show breeds that lurk behind the "pure" breed and, thus, not what you expect.

I can't say much about the horse DNA test as I've never done one (and honestly didn't know it existed!) but I can definitely vouch for the dog DNA test. I think that the biggest reason so many people get crazy results from it is because the sample was contaminated or the instructions weren't followed extremely carefully. You have to make sure that the dog hasn't had anything whatsoever in its mouth for several hours before you take your sample, or it can get contaminated and your results will be wonky. That's pretty tough to do since dogs like to lick everything and you'd basically have to watch the dog the whole time to be sure.
I was extremely excessively careful about that with my dog and followed the directions to a T and got results that I have no doubt are accurate based on his appearance and personality. It really answered a lot of questions for me about him! I also tested my mom's dog and was just as careful and her results are definitely clearly correct as well.

What is used for the horse DNA test sample? I imagine there's no way that it would work with a cheek swab like the dog one is done, lol
But if it's something like a blood test but the same sort of technology is used as the dog one, I would bet it would be pretty good.

Yes, that is used in all stock horse registries, and that,a s far as I;m concerned, plus testing for genetic defects, is where DNA testing has both merit and is very accurate
When you pull hairs on basically a grade horse, you can have a wide range of genetic influence, not to mention, most breeds are not 'closed purebreds, with years of no interbreeding, thus share common genetics
Most breeds are man made. Someone started a registry, and those horses int here often evolved from diverse genetics. Many light horses have an Arabian influence., gaited horses, even draft
Just because some organization then gathers these horses together, and calls them Paints, Apps, AQHA, or what have you, doesn't mean that other genetic influences that were used to form that registry, then leave that breed!. heck, i raised Appaloosas, with Mighty Bright breeding, thus there sure was Paint genetics way back there,(Bright Eyes Brother), and even if I hoped they would not be expressed, at times they did, to the point I could not register one filly, as she had a huge white 'paint' patch on her belly

FOUND IT!!! i have it in my email. PM me if you want it in email original docs form and i'll forward it.


DNA sampling:

We need 30-50 pulled mane or tail hairs with the root follicle attached. You may use

either mane, tail or both, whichever is easier. Hairs must be pulled straight out to ensure

follicles come out of the skin. It may be best to pull 5-10 hairs at a time rather than larger

amounts. To send, write information about the horse on the form provided, on a blank

sheet of paper or on the outside of a paper envelop. The information is the type that

would be on a registration paper. At the bottom of the form or paper, tape the hair

sample to the paper with clear tape, or just put the hair in the envelope with information

on the outside. Do not tape over follicles. Extra hair can be trimmed. For single samples

you can fold the paper and mail like a regular letter. If sending multiple samples, place

each sample in an individual envelop and put all envelops in a larger envelop or box.

You only need to fill in the boxes you know the information for.

My mother had a breed test done on her purebred Peke dog. When she sent it out she stated that he was a mixed breed. The results came back 100% Pekingese. I don't know where she sent it to, I'll have to ask. I think that a lot of these places that test for breeds on horses don't have it quite all together.

Boy that is worth $25 just to see what they would say about my two without-a-doubt-registered Tennessee Walkers.

That said, it's the part about pulling all those hairs and the follicles that gets me, lol

There's something about that, that gives me the heebeegeebees.

I can dress a leg with a punctured artery and blood squirting everywhere; just the thought of pulling those hairs makes me gag:beatup:

I know I know, we all have our idiosynchrosies, this is mine:bowwdown:

Not to distract from the thread but I'd highly recommend it if you are curious about any of your dog's behaviors! When I got my dog, we were pretty sure he was either pit bull and dalmatian or american bulldog and something else, but we were also curious what else must be in there because he is a total bird dog and naturally points and retrieves. None of those breeds would generally have any hunting instincts. So I tested him and his main breeds came out as pit bull, dalmatian, and vizsla, which is an all-purpose hunting breed that is kind of rare but I've actually seen a lot of them around where I live so it makes sense that he'd have that in him. I read up more about vizslas and it described his personality exactly. So he got his appearance from the pit and dalmatian, but his personality from the vizsla. I'm really glad I did the test! But definitely be sure to follow the directions super carefully or else it will end up being a waste of money like some others have experienced.
And mind you, they don't ask you to send in pictures of the dog or anything. All that was sent in was his name, I think maybe his age and sex? And the cheek swabs.

Here's my boy all buckled up and ready to go on an adventure in the car.

This thread is really making me want to test my boy Rocky. We were told he was purebred RMH but I've always had my suspicions about him being a cross. And my mom's horse came from a rescued herd of abandoned Morgans but she doesn't look like a purebred Morgan to me, I'm not even convinced she has any...hmmm....

Rocky pony, . I also don't want to hijack but, look up the Catahoula Leopard Cur dog breed.

Your dog has the same "flying nun" ears as my Catahoula/Pit Bull mix.

My other Catahoula is either purebred or has Fox Terrier in him.

Both mixes are used in the south for wild boar hunting or cattle herding.

They are tracking dogs not gun dogs.

What I call "Rottweiler intelligent". The younger one that is mixed with Pit Bull is stubborn as the dickens, lollol. He will say "and why not" ten times more than my Rotts ever did.

Anyway, I think it's Abbey Kennels that breeds pure Catahoulas. I think you will be surprised.

AKC doesn't recognize them because the "physicality of the breed structure" is all over the map. My two are polar opposites in that regard.

Oh I'm very familiar with 'houlas, one of my closest friends is a huge fan and has had many of them. Great dogs! Very energetic and wild, lol. My boy definitely isn't one though! His ears are typical pittie rose ears (other than the dalmatian coloring). They don't flop forward like a houla, they always go back or to the side. I don't have many pictures of him looking alert because he's a lazy bum, but they look like this dog's when he's alert.

I did something similar for my dog and it seems that the accuracy of the results depends on the completeness of the breed profiles the company has in their system. The test was very accurate for my dog, but my friend used the same test and got wildly inaccurate results because at the time her dog's main breed was not in the system. I'm guessing it's similar for horses and might throw out something random if it doesn't recognize some of the DNA?

Many mustangs have interbred for many years, having a very diverse genetic background, so to try and identify them ,far as any breed is a crap shoot
Heck,you don't even know, breeding one generation of two very different horses as to what you might get, thus your horse;s size is a mote point! That is how breeding hybrids differs greatly from breeding horses with a more fixed genetic background
I know of full siblings, half draft and half TB that look nothing alike.
One has the refinement of the TB, and the other has neither the size of the draft parent, just the bone and coarseness. You would never know it was half TB
My friend has a good sized horse, out of a pony jumper. A draft stud visited her place, and bred that pony mare. The resulting baby grew to be a 16hh horse.
Heck, you must know families, where the husband is quite tall and the wife is short, with their son being taller than either.
DNA typing of wild horses allows isolated herds to be identified, where little influence from other horses has been added to their original Spanish heritage

Makes me curious...as someone stated earlier, Arabians have been being bred pure for a very long time. My gelding is registered half arabian, but that is only because of one infusion of outside blood 5 generations ago. I'd love to see if I could find out what that one horse was. All AHA has for info is that the horse's name was Sioux.
