That's cool! I'd heard it would be available soon. Too bad I'm stuck in the land of dark bay mares (seriously, dark bay is my least favorite color) and won't ever need to test for all these neat color genes. Red and agouti are about as far as I could go.
That's interesting... I have a silver buckskin paint mare. (Ee Aa nCr NZ) She was originally registered as a dun because of a dorsal stripe. The stripe looks like countershading to me, but sometimes I wonder... One of her foals, out of a dark bay stallion, had a VERY distinct dorsal stripe showing through his baby coat... Not sure how it shed out though.
Might be worthwhile to have her tested. Boy would that just be insane if she carried dun too? Several of her foals are registered as duns. I just figured they were actually silver.
She's a rarity, that's for sure! Forgot to mention she's overo too. Her body is a really rich caramel brown, her legs look almost dark burgundy. Her mane is pretty dark because the cream gene has a tendency to "cancel out" the silver effect on the mane & tail. There are pictures of here here:
I might try that. I think I have a red dun colt. AQHA registered him sorrel but I think that is because his dam is bay. What they don't know is that she has quite a dorsal stripe and is likely bay dun. Other offspring of the sire have been red dun. So I wonder. maybe I should test both mare and foal. of course some say they must have more than a doesal stripe to be dun--other barring.
I have a number with a lot of white on them that are hard to tell what they carry under all that white. Seeing them in their foal coats helps as dun factor markings can be more obvious (as well as more misleading) right after birth. Generally though, in our breed, foals are born with dorsal stripes and shoulder/leg barring and it indicates dun. A good example was our first foal, Ricochet who was a lovely tan color with primitive markings and he roaned out to where you can barely see any sign of the primitive markings now. Seasonally he runs from nearly white to a tan color.
This is what Ricochet looked like last weekend at the stallion show:
There's just one problem, the test is not an actual test for the Dun Gene itself, yet. They are looking for "markers" which is not quite the same thing. They are asking for hair from at least one, preferably both parents to be sent along with the subject horse. I'm not sure exactly how that works, but there's no guarantee it's 100% accurate. From what I heard they are going to keep looking for the actual gene, though, fingers crossed they find it soon.
He's so sweet, I just love his disposition. I think he'll be a great cross with Angel. She's doesn't have a mean bone in her body, but she's pretty fiery! You'd swear she was at least half-arab based off of her looks, brains, and attitude!
That's pretty cool -- I have a young gelding by a dun stallion, out of a rich chocolaty bay mare. The gelding has the rich chocolate color with no signs of dilution, BUT he has shoulder barring, leg barring (barely, since he's tobiano) and a dorsal stripe. I've always wondered.

Did you know that if you say the word "GULLIBLE" really softly, it sounds like "ORANGES"?
it's not the edge of the earth, but you can see it from here
Talia--if the sire is homozygous tobi--where are the 'plain' overo and chestnut etc. %s coming from in your analysis?
Or is he homzygous black? (no, I see chestnut there too.. )
I did not know the new test wasn't a strict genetic test. But I'm guessing the more we test for markers, the more it leads them to the genetic test? Or is it apples and oranges? Would love to 'help' find the gene, you know?
If they are able to run a test that shows probability that the horse carries the dun gene, they have pinned it down to one chromosome, and probably one area in that chromosome. They probably have a test that looks for a gene that they know is really close to the dun gene, because it goes with the dun color if the chromosome has a recombination event. The more samples that they get, particularly if they can get several from a family line where some have the dun gene, and some don't, the faster they will pin down the actual gene itself. So they would probably love it if you can get together with a pool of other owners of get from the same stallion, and all send your samples in at once. For instance....
