Has anybody seen this one yet?

An "oops!" spot only. Not heritable, wont be passed on ...

"Technical" name for it is a somatic mutation

[KBEquine]

Interesting. How can you tell that's what it is?

Yes, other than a small star, this is her only white marking. Saw Big Brown run at the Ky Derby and noticed he also has one. She does have two other siblings by the same sire who also qualified for regular registry APHA. Donna, I'd love to attach a couple of his photos if you can give me a crash coarse on how to get them on here. Pretty flashy. He's currently a stallion and the owner would love to find a new home for him if anyone is interested. They are considering gelding him to make him more desirable. He's not as tall as "Spot", but definately got more spots. We had hoped some of these genes would come through.
Really nice mare. Hoping to get her into a riding home.

We can tell by the shape, location, and other markings (or lack thereof in this case).

Donna,

While the spot isn't inherited like sabino, or splash, there does seem to be an inherited component to the mysterious white spot. It shows up randomly in some Northern Dancer lines, and I'd have to go back and check pictures, but may come from the Darley Arabian. This white spot tends to show up on the shoulder or the barrel on one side and seems to be unrelated to any other white markings. Also it doesn't seem to be related to belly spots.

Just my observations on this.

(emphasis added).

I know you can tell . . . and I'm trying to learn how you can tell.

I was hoping you'd help to educate me.

Oh I'm sorry, I kinda thought that was an explanation. I guess I was unsure how much you wanted.

I'll come back and post some detail in a little bit.

Thanks - I just came back & looked & realized my post sounded a little rude - sorry.

I really did want to know what it was about the shape & location that clued you in.

Sorry I apparently forgot to come back to this.

The Shape: This is just not the shape caused by normal white markings genes. Virtually all overo genes cause spots that move horizontally and have rough and/or jagged edges and overall shapes.

The Location: This is also just not a place the overo genes choose to spot then they cause single spots. Notice how all the ones I've posted are all well forward of the flank. Most of the time single spots come very near to the girth line or over the ribs. Others come somewhere on the neck.



an extreme case:


Also note how jagged those spots are as well.

The other markings: Note how every horse I've shown so far has significant other markings. To find a horse with a spot the size of that mare's that has no more markings than her (a tiny star only) would be nearly impossible. I've never seen one, especially not one that also had the other features I've mentioned.

I think that's about it.

Great post. Thanks for taking the time - I really appreciate it!

This mare does have one other puzzling trait. Both eyes have pink third eyelids, and her 2009 solid colt had the same. Her half brother by the same stud was a splashy chestnut with stockings into the knees and white up past the gaskin. Also a huge,wide belly splash that continued up his right side. Wish I knew how to attach his photo. Huge blaze and lower lip as well. Their sire produced three regular APHA registerable offspring in all. I've seen eyes like this on sabino type chestnuts, but never on a bay with so little facial white. Any thoughts on where this came from?

[TrueColours]

Hmmm ... Audrey - could she be frame then but not express it? Like the stallion "Spot" by Racey Remarque that really has minimal to no white on him but he tested postive for frame and sabino and throws some really wild looking babies as well!

Apparently Spot's APHA qualifying white spot is on his penis or on his sheath somewhere as none of his other white markings qualified him at all

Framed - I pull my pictures that I post off my website. I know that there are some free picture posting sites you can upload photos to and pull from there but dont have a clue what they are or how you do so - hopefully someone else can chime in on this one ...

[summerhorse]

send any pictures to me at summerhorse.geo @ yahoo.com (take out the spaces) and I will post them for you!

I love this mare, keep seeing her for sale and keep never having enough money! sigh...

[framed]

She is not frame. We tested her and she is Ee/AA/- n/n. Still, the eyes are different.I'll send the photos to summerhorse as mentioned, or maybe I can put them on one of the photo sharing sites to get a link I can list on the forum. I too am very fond of her, but I want to sell one before my foals arrive, so we have three for sale. She has the most inquisative and engaging personality- a real pet. On the fence about breeding her back to our stallion if she doesn't sell soon. Not sure I'll get much color from her even if the frame gene "hits".
