When you think about a wild horse, what’s the first thing the comes to mind? Most of our minds wander in the direction of a horse like Spirit, Stallion of the Cimarron, or maybe a horse that looks somewhat like him – perhaps a dun with a long mane and tail flowing in the wind. Well, here’s all you need to know about the beautiful dun horse color.
A dun horse rates a solid 10 for flashy and unique. These horses can be identified by their primitive markings such as dark or black zebra-striped legs, a dorsal stripe, black edging around the ears, a black shadow like a mask, and stripes on the withers. The mane and tail are usually the color of their dark edging.
There are two different types of dun horses: a red dun and a classic dun.
Red duns have a base coat color of sorrel and do not have the black points because sorrel is the base color. However, they still have the striping characteristics.
Classic duns have a bay base coat color and these horses can range from a pale tan color to darker tan. Classic duns have all the black points.
Where does this stunning dun color come from? Well, if you remember the article on Cremellos, this glance at phenotyping and genetics will be a breeze.
The dun coloring comes from a genetic mutation – a dominant dilution genetic modifier, making the appearance, or phenotype, of the coat seem diluted. This gene only appears on horses with a base coat color of red and black. Where does sorrel and bay base coat colors come from? Sorrel comes from a red base and a bay color comes from black.
Dun horses can be tested to find if they are homozygous for the dun gene. If positive, no matter what color a dun horse is bred to, the foal will be dun.
Dun colored breeds
If a dun horse makes you think of a wild horse, your thoughts aren’t that far-fetched! The wild Asian horses called Przewalski horses are mostly dun. Other horse breeds that are common to be a dun color are American Quarter Horses, Icelandic Ponies, Highland Ponies, and don’t forget Mustangs! (Close to Spirit – he’s a dunskin.)
Are Dun and Buckskin the same thing?
No, dun and buckskin coloring is not the same thing. A buckskin color is produced by a genetic mutation, but of a single shot of the cream dilution gene on a bay base coat color. The cream gene is also responsible for the Palamino color. A buckskin can have a dorsal stripe and the dark mane and tail. However, duns need all the other characteristics plus the dorsal stripe to actually be a true dun.
It’s so interesting to think that all the different colors of horses can come from a single genetic mutation. Something so small can have such a huge impact on the appearance of a horse, such an impact, you can’t help but fall in love with a dun horse!
