This is my Spanish Mustang mare

[img]http://farm3.static.flickr.com/2429/3657390574_245388f3aa_b.jpg[/img] Sire is a possible dun carrier reg. buckskin roan, but his dam had a partial dorsal as did he and her dam had a dorsal... Dam is a grulla. You're about to be a my new best friend. This horse has changed color incessantly since I bought her she's only three, well, what do you think?

It is possible she could be a faded black roan but I don't think so. I would expect her face to be faded somewhat along with the rest of her and its not.

[quote="Fledgesflight"]If that (OP) mare is not a Black Roan Dun I'll eat my hat!!![/quote]

oh! we might have a goat as well as a duck! :rofl

the more I look the more I agree with grullo roan. especially how it looks more like a black roan in winter coat, like a grulla would be more black and silver in winter and be more tan in the summer. The body does keep making me think of a sooty buckskin the way the tan is showing low on the belly and hip but the face just keeps throwing that out, there should be some tan highlights if it were a buckskin, thats where even the sootiest buckskins show that they ARE buckskins.

I don't think it includes dun, this is the list from their website.
# Cream dilution
# Red (Chestnut)
# Tobiano
# Silver
# Sabino 1
# Agouti (Bay)
# Champagne
# Hyperkalemic Periodic Paralysis (HYPP)
# Lethal White Overo (OLWS)
# Glycogen Branching Enzyme Deficiency (GBED)
# Junctional Epidermolysis Bullosa (JEB)
# HERDA (HERDA-QH)
# Polysaccharide Storage Myopathy (PSSM)

huh I just looked at the UC Davis site about the dun test. They aparently need sample from the parent, 3 generations of pedigree, and a photo of the horse and the markers found in PREs, Andalusians and Lusitanos is apparently different. Which depending on the origin of your horse's dun could throw a loop. :hammer
I supose it wouldnt hurt to try :|

But go for agouti and cream first. That might clear it up. The big package is cheaper but you probably have to wait long (as they are doing the batch right now?)

ACC how the heck did they determine that Lacy was NOT a dun? :?:

No DNA Diagnostics just finished their batch. You'd have to wait until they get 50 more samples before they run them again. No telling how long that might take.

I would just test for extension, agouti, cream and dun. Since UC Davis is the only place doing dun and they combine extension and agouti (saving you $10) I'd probably go through them. It would cost $115. However, it would still cost you $90 if you did wait for DNA Diagnostics because you'd still have to pay UC Davis $50 for dun. You'd get faster results with UCD too.

Morgan: As you know I don't have ANY information on Lacy. They did her test based solely on her hair. I'd say her hair and her photo, but her photo is what landed her on the supervisors desk because the people who ran the test questioned her phenotype as compared to her test results (she LOOKS dun). So who knows. I have alot of faith in Horsegen, and she has alot of faith in that test... but I don't think I do. At least not yet.

That's exactly what I think. Or possibly even a separate mutation of dun (I know of one researcher who very strongly feels there are multiple dun mutations). However, according to Horsegen, their test has been accurate enough to make another mutation highly unlikely (at least in QHs and Paints), however I would not be surprised to find out there was another marker combination. I mean the original tobiano test got a few wrong every now and then and they were able to improve the test as they found these tobianos with abnormal markers. But see tobiano is so easy to tell visually most of the time so they could change their test for a horse who fit the phenotype but seemingly not the genotype. Dun is a bit subjective (at least comparatively speaking)... so I definitely think it's possible.

CMhorses Fri, 06/26/2009 - 21:53

That would be amazing! Then you could take that to the genetics labs.
I still think Lacey and possibly Smokey have some kind of a dun mutation.

shes is lovley! such a kind head! :love

I think shes a grullo roan. Dorsal looks distint to me and I can see leg barring. Roan does hide dun markings to some degree. Shes looks like a twin to a horse here thats a grulla roan. From a homo (for dun & black) grulla stud and out of a red roan mare. Now I gota just find the piccys!
