The color of the body should be a slightly "muted" color if compared to non-dun horses of the same color. Of rather - it is oftenly slithly muted or a little diluted, but there are of course exceptions, and sometimes it's just a little difficult to see the difference. If you could see a very distinct true dorsal stripe and a little diluted coat, then it might be an indication of dun. The head is oftenly a little darker than the major part of the body, as well. To fully know if it's a dun and it has a lot of white, a test might be the way to go though.
Ah, well the vet fortunatly don't need to take the test. You just order one online, pick a few hair from the horse and sent it to the lab. A few weeks later you got the result I've tested two horses for other things that way - very easy to do! The lab is a serious one and you could trust the result
Well, in that case there's no need to depend on the other caracteristics If it's a really distinctive, clear dorsa stripe with sharp edges and not a false one, it's probably enough to tell that it's a dun
I'm not completely sure, but I think the fjord foal you have to the right is rødblakk(maybe with one yellow gene, or just light bacause it's so young) Gulblakk usually don't have the dark stripe so visible if you see here: [link] This one's a rødblakk I think: [link] Now... take it with a pinch of salt, I'm no good at genetics, but I've studied and seen a lot of Fjords... xD
I wrote Gul? Ah heck, that's definitely one that should be changed I uploaded this for the first time ago but I really thought that I had checked everything enough times by now to notice missplaced terms and colors. Apparantly, it's not so... But you are correct - that's another one that should be corrected!
Do you happen to know what causes false dorsal stripes since it's not a dun gene? My mare is bay and has a dorsal stripe. I've always found it odd. On a side note, I've always wondered if she would be considered a seal bay or just a bay? This is her: [link]
Also, this has had me wondering for a while. Is this mare black or just a really dark bay? [link] I could swear that if you look closely at her body you can see hints of red, while her legs stay black. But I'm not sure. Her owner refers to her as "black" and she's registered as a black Morgan. But I could SWEAR I see red hairs in there. I've read that many "black" horses are actually just super dark bays. Do dark bays get classified as black?
False dorsal stripes aren't uncommon in bay and brown horses. They don't even have to be sooty to have one, so exactly what's causing it I'm not sure of. There isn't any known specific gene that causes it though. I'd call her a dark bay, judging by that photo
Judging by the photo of the black horse, I'd call her black. Bu then again, I've only seen that specific photo, and a single photo can actually look quite different depending on what screen you have A black horse doesn't have to be extremly black. Some stay completely jet black, while some get slightly bleached or fade a little. Compare with this friesian: [link] and another: [link] Another: [link] And a black young arabian: [link] IMO the horse in the photo is black, but then again - I've only seen a photo
It's quite easy to check if she may be a dun. One parent need to have been dun. I none of them were dun, it's impossible for her to be dun. It's quite easy to rule out in case none were dun, in that way Sometimes breed can also rule out Dun. Many breeds doesn't have dun in their gene pool.
Grey horses tend to have dorsal stripes, even if they weren't dun to begin with. If you look through my gallery, there are a few of Itz where you can clearly see the false dorsal stripe of his. Leg barring is quite similar, and can also appear on grey horses. It might be easier to tell from an older photo of the horse and see what it looked like when it was at an early stage of greying out
Hey do you think If I sent you a picture of my horse. That you could tell me what she is. Her mother was a dun and her father a palomino. But she has a half strip, its very light and it only comes to the middle of her back.
I'd actually want a second oppinion from someone on this particular horse, because I'm not really sure That she's buckskin is clear, but wether or not she got dun as well is hart to tell from the photos. From the ones you linked to she looked a bit dun, but then I looked at some of the other in the gallery, where she looked more like a classic buckskin. The dorsal stripe could just as well be a "fake" dorsal stripe, which is something that I've seen inmany breeds, and from the photos you provided it's difficult to tell what it really looks like. There's also some odd lighting in many of the photos, which makes it a bit hard to tell. I'd suggest that you'd go ask JNFerrigno, who's better at stuff like this than I am
hehe, glad that they could be to some use!^^ I didn't want to go into all the details - there are way better sites who discribe all the details - but I just wanted to show some of the different colors horses can have. Very glad that it worked as I wanted it to!^^
Oh, most definitely. They are quite different! Thanks to all that selective breeding
Haha, I'm used to shortening it for non-genetics people frequently XD You should have heard my color genetics presentation that I did for my senior thesis! I think half my audience was completely lost anyway XD
But is it truly from selective breeding? From what I've understood, the fjords were at one point close to extinction, and the only individuals left were the dun ones, thereby causing the breed to be true duns. Have I got this all wrong?
hehe, well that explains your skill in making it sound so simple! Heck, I make everything sound too complicated!
