Light dun markings

This is a proven dunskin and those who have seen him in person say there is no hint of dun.

So is it just the creme playing with the tone? She's a yearling now, will she change much as she matures?
Her mom is Walgarth Ismerelda who is a bit darker but not those black strip duns.

I suspect so, yup. I also suspect she'll darken some in another year or two.

Look at a Fjord for some seriously light dun markings. All the Fjords that I have seen that I remembered to check (>10) have their dorsal fade to nothing in at least one area down the back.

This is one of the reasons I do not dismiss some horses that otherwise we would call countershading.

She is SO cute!

Yes, Fjords can be that light too, even the ones without Cream.

Thank goodness! I was hoping the test results were not accurate!
With her winter coat, you can't see the stripe except if you look at a certain angle.
I like that it's light, but was concerned about countershading.
How do these markings differ from counter shading?

[quote="Andrea"]I've been searching all over for duns with light light markings.
My yearling's markings are there, but so light. She's got a nice wide dorsal but it fades as it gets to her withers. [img]http://i100.photobucket.com/albums/m26/…]

Nuh I reckon she comes across as very dun, she's also very cute!!!

Peronally I think they are the same, except dun diluting the way it does make it's more obvious.

I would think that they are inheritable as opposed to random.

Let's see....

Countershading - 1. a form of adaptive camuoflauge where the coat color is darker dorsally; 2. a term applied to any pattern of darkened hairs in the coat color

Dun - a horse with the dun mutation

hm. I would imagine that both are inheritable. So one is camo, and one is a specific mutation.....?????

The way I figure it, all horses have the potential for more or less dun factor, dune gene just makes obvious, as does other dilute genes

Interesting! So in fact, all horses could actually carry it, but only some have the gene that dilutes the rest of the coat to bring it out more.... ?

Good stuff!

Thank you! I can't decide if she's cute or weird... Her neck is very skinny so her head looks large and she's lighter then what I like section As to be. I'm hoping she'll fill out a bit. She's only one, so I still have hope!

Andrea you didn't want her to be dun?

DunCentralStation's opinion is that EVERY horse has primitive markings. Dun does not cause primitive markings, it simply dilutes the coat AROUND the primitive markings leaving them obvious. Other genes have the potential to do this, but only rarely do they actually do it. Sooty seems to be attracted to the primitive markings and can darken them up and that's probably where you get the very noticeable countershading.

While she may be an example of horses we would normally call countershading actually being dun, this one tested non dun (still not sure I trust that test). It seems to swing both ways. At least yours has another dilute to explain the paleness of markings though.:

So really it is like a tabby cat, all horses have the dun markings but only the dun mutation and sometimes some others colours show them?
There is a girl who goes to the RDA where I volunteer who has a little chestnut arab mare with very noticable stripes on her legs.

That's her theory, yup. Some people don't buy it. I'm on the fence.

I've always believed that dun's effect was simply by diluting everything but certain areas, leaving those areas the same color the horse would have been if not dun diluted.

wow she look soooooo dun ACC!!

Ya...I really think that if Lacy isn't dun? Then there is something else to look for. The countershading enhancer or something.....

I think Lacy is the dunniest non-dun in existence :rofl

I'm tempted to retest her, but I doubt it would change anything. I WILL retest her when they find the actual mutation. I also plan to send hairs to Hoofpick as soon as I remember to pull them. (Depending on what her foal looks like I may test her too.)

For now I would just call her dun anyway, test be damned. If it walks like a duck and quacks like a duck....

Still haven't found an answer to her odd peach body color either (no sunbleaching, she's in during the day).

shes a strange colour for a non dun! lol

This is Lacy, and she tested neg for Dun?

Indeed.

In fact her paperwork got lost at UC Davis for a bit because the person that had run the test was surprised it was negative based on her photo and put it on the supervisors desk for him/her to double check. They found it when I called to ask but apparently the supervisor decided to go with non dun anyway.

Hmmmmm.... yeah that sounds like possibly they got the wrong result, he dorsal stripe is light but distict.....she doesn't have any of the primitive marking on her legs but I know in red duns they can be very light, on her legs Annies don't show well in the winter but in the summer they show sho pretty well but still light, that is because her summer coat is much lighter than her winter coat.

I've looked and looked for leg bars and, except when she's sooty, they're just not there. But I have seen a good number of known red duns with no leg bars. *shrugs* Your red dun is much more chestnut looking than my chestnut (not counting her factor). :rofl

Well you were saying that the theory is that the coat is diluted around the base coat so if the base coat is really light then maybe that's why they dont show up as well somtimes. Annie is redder, she looks like a chestnut to me in the winter but in the summer she looks red dun to me because her legs bars and dorsal stripe shows up so much better and her coat does get pretty light and creamy looking.
