Beautiful Pinto horse...his breeding as it says is an Arabian/Quarter horse cross..what the Spirit part of the Quarter horse name refers to I have no clue, except maybe it is a bloodline designation.

There is also a color registry where the horse could be registered as a pintabian, since it is a half Arabian that sports a pinto coat. Pinto refers to a horse with a spotted coat color pattern, not a particular breed. He could also be registered in the Arabian Half-Arabian registry. So he could actually be a double registered horse.

Homozygous refers to a genetic equation in which there are two copies of a certain gene present that dictates that all offspring will inherit the particular trait the gene pair is responsible for.

In describing horses as homozygous pertaining to color, it means that all foals the stallion or mare produces will be the homozygous color, such as in the case of this colt, black.

It's a complicated formula that there is genetic testing for, thus allowing a stallion owner to honestly advertise that their stallion is homozygous for a particular color.
Thus if a breeder wanted to breed for a specific color, such as black it is usually guaranteed the foal will be black.

In order for a horse to be homozygous both parents must carry a copy of the gene, so although the resulting foal may be black from a black homozygous stallion, that does not mean the foal will automatically be homozygous as well, unless the dam also carries the gene.

Whew!! More information than you needed? If you are really into the scientific exploration of these genes and how they work to produce color you can further torture yourself at the below website. It has a fairly easy to understand explanation of the gene codes and what colors produce what when XY is bred with YX:confused:.

Thanks for the answer Oz , that's very interesting as i have always wondered how they could guarantee a certain colour in the foals, from memory there is a certain two types of horses for a Palamino am i correct.
Between you & TWH i am learning a lot about horses

Wow, Jilly..you're really taxing the old brain tonight...you'd better study all this because there's going to be a test later. BTW like your little rearing horse.

Now you're talking heterozygous breeding...crossing two palominos or a chestnut and a palomino have a 50/50 chance of producing a palomino. This is just basic and there are more factors involved, but you can't guaranteed a palomino color, like you could a homozygous breeding.

Also just FYI, there are several devastating diseases in certain breeds and bloodlines that can now be genetically tested for. Even though some horses are carriers of a certain genetic disease, in some instances, with testing it is safe to breed them on if they are bred to a non-carrier. There are some very valuable proven show and performance horses that are carriers, that in the past would have been put down if they were known carriers or at the very least, gelded so they couldn't pass the disease on. Most reputable breeders now test their breeding stock to ascertain if they are carriers for the diseases and only breed to non-carriers mates.

Jilly,
Oh, and tobiano in the description of colt in the above picture refers the type of spots in a pinto or paint coat pattern. There are several different types of spotted coat patterns such a overo, tobiano, sabino, tovero, splash and probably some others. Some coat patterns can be DNA gene tested for and some can't.

Now you want to know the difference between a paint and a pinto, dontcha?

This could be never ending.
 
I love the baby critters. Retired jockey had horses when I was living at the winery and sure was fun watching the new foals. Now, still living in horse country but no births as of yet . . .
 
TWH..Thanks for the explanation of the Spirit Quarter horses. I suspected it had something to do with bloodline breeding.

TWH:
That drop-dead gorgeous fella Jilli posted could go into the half Arab registry but being a 50-50 fella, it will de-value his Get regardless of which breed they put him with. He's been tested so they've put a lot of thought and effort into him.

Well, logically you would think that would be the case, but actually half-arabs depending on the flashiness, or in the case of Saddlebred/Arab crosses with higher leg action than purebreds for English Pleasure can sell for far more money than purebreds. Color breeders would breed their purebred mares to him for the color. A few years ago, the half-arab pintos were very much in demand in the western pleasure show ring, bringing big bucks. I don't know what the climate is today, since breeding has all but dried up in the Arab registry. In the half Arab registry, one parent must be purebred, and it doesn't matter which one. There are many half Arab classes in A rated shows, Regional and Nationals shows.

So yes, this pretty fellow has a chance of a nice future in the half arab world if they are still in favor in the show ring. But regardless of color, a good horse is a good horse and if he can prove himself in the show ring and the breeding barn, his future is rosy. If he is a no talent that cannot pass on good conformation, temperament and soundness, he will trot off into the sunset like so many before him.
 
TWH:
However, unless you know for absolute 200% fact that foal is that adult horse, I would like to ask how the face markings changed so drastically. Face markings never -ever change.

The markings on the side don't totally match up either -- there's a white spot on the upper leg of the adult that is not on the foal, plus the black pattern extending from the flank area into the side of the barrel don't match.

Black in the tail doesn't match, nor does the coloring across the topline.

Without question both are drop dead gorgeous but did you maybe grab the wrong picture for one or the other?

OMG..TWH, what an eagle eye you have, and your are absolutely correct. I really didn't study the markings, but while markings can appear smaller on the head, once a foal grows, the shape and pattern does not change. Same with body markings. How did you find out who this colt was, since Jilly didn't post that info. I wanted to check out the website. From the description under the picture I was confused as to whether they are selling him, or are breeding him to approved mares only. If it's to approved mares only, that's usually what they specify.

I saw that but thought i would stay quiet , the blaze is quite different on both of them, i think what the advertiser was trying to do was show a foal from the stallion

Jilly...This makes sense. I was just taking it at face value and answering your question without looking too closely for a comparison.

At any rate they are both lovely horses, and I enjoyed giving you the abbreviated lesson in color genetics.
