Difference Between Dun and Buckskin

July 2022 · 7 minute read

Geneticists once thought that the Dun horse was the consequence of a dilution gene and that mating Duns and Buckskins together frequently resulted in the birth of an Albino foal. Recent research has shown that this is incorrect. As far back as written history of the animal is accessible, the authentic Buckskin horse may trace his heritage through a direct line of Dun or Buckskin colored predecessors. 

Dun vs Buckskin

The main difference between Dun Horse and Buckskin is that Buckskins have yellow bodies with black manes, tails, and points, similar to bay horses. Duns, on the other hand, are reddish-yellow to mouse grey in color, with frost on the mane and tail and archaic patterns including a dorsal stripe, shoulder blade stripes, webbing on the forehead, and leg stripes. People frequently mix up the two hues. There are, nevertheless, substantial variances, some of which are inherited and others which may be seen.  

The dun dilution gene affects all coat colors (not just bay), but in a bay horse, it causes the coloration that most people mistake for buckskin.  A dorsal stripe is sometimes a gift on Dun creatures, and lots of even have to mark on their shoulders, legs, and forehead. Chestnut (red dun) and black bases are likewise wedged by this dilution sequence (grulla or grullo).

Buckskin is a coat color that resembles tanned deer hide and is caused by a bay horse with the cream dilution gene. Silver dapple and sooty are two types of buckskin. A gold or brown coat with a black tail, mane, and lower legs distinguish these horses. Buckskins are thought to be more resilient, strong, and determined than other horses.

MarkingsA bay dun horse is a tan horse with black points with all of these markings evident, with the dorsal stripe running the entire length of the horse.A buckskin horse, on the other hand, is a brown horse with black points that lacks any historic markings.
ColourA dun dilution gene was put into a bay base color horse to produce the Bay Dun horse.A buckskin horse’s color is the result of a single cream dilution gene on the bay base color.
AppearanceBuckskins have black manes on tails, stockings, and dorsal stripes on their bodies.Duns have a brown or dark grey dorsal stripe on their backs, and their bodies are sandy brown or mouse grey. The mane color varies. So does the tail color. This variation is from horse to horse.
GeneThey have dun dilution genes.They have a cream dilution gene.
VariationThe dun dilution gene affects red dun horses, as well as grulla and grullo. If a Buckskin horse’s base color is brown, the cream dilution gene causes it to turn golden.

What is Dun?

Dun is created by diluting the basic color and adding rudimentary marks (stripes on legs and one along the back). Dun was the color of all horses’ coats when they were born (“wild type”). Various colorings occur depending on the horse’s basic color: Red Dun (chestnut), Yellow Dun (bay), and Blue Dun (blue) (black). A dun horse features a dark dorsal stripe on the middle of its back, a dark-colored face and limbs, and cross or horizontal marking across the shoulders or on the rear/back of the forelegs. The color of the body is set by the genetics of the coat color.

Duns with a chestnut foundation color might seem light tan, whereas those with a black base appear steel grey. The undiluted base coat color is frequently used for manes, tails, primitive markings, and other dark regions. All other coat color alleles might interact with the dun gene. 

The primeval or wild sort color of horses is meant to be Dun. Several of the equines seen in prehistoric cave paintings, like those in Chauvet Cave, are dun, as are various closely connected species within the Equus. The Equus caballus przewalskii, onager, kiang, African ass, an extinct plains equine race referred to as the quagga, and an extinct horse race referred to as the Equus caballus gomelini are among them. Zebras are a kind of dun with hair that is practically white and primitive patterns (like striped leg barring) that stretch over the entire body.

What is Buckskin?

Buckskin refers to a hue that mimics specific hues of tanned leather and is employed to explain the hair coat color of horses. Buckskin may be a term accustomed to explaining the hues of assorted dog breeds. The coat of the horse is brown or gold in hue with black spots (mane, tail, and lower legs). The cream dilution factor acts on a bay horse, inflicting buckskin to seem. As a result, a buckskin has one copy of the Extension, or “black base coat” (E) factor, one copy of the gnawer factor (A) factor (see the bay for a lot of info on the gnawer gene) that compass the black base coat to the points.

The body of a buckskin horse is generally pale cream to golden tan in color (similar to buckskin leather), with black points (mane/tail and legs), and both their skin and eyes have a black hue. Buckskin horses are available in a range of breeds. Not all breeds have a minimum of one parent that carries the cream factor. Though Buckskin is often classed as a color breed, coat color cannot ever be an abiding true-breeding feature due to its genetic composition, which depends on possessing one, not two copies of the dilution allelomorph.

Main Differences Between Dun and Buckskin

  • A Bay dun horse is a tan horse with black points and every one of those markings visible, with the dorsal stripe going all the way to the tail. A buckskin horse, on the other hand, is a tan horse with black points and no evidence of ancient markings. 
  • The major distinction between these two horses is that their color dilution is caused by two separate genes. On the bay base hue, the Buckskin is the consequence of a single cream dilution gene. The Bay Dun horse is the product of a dun dilution gene being inserted into a bay base color. 
  • Buckskins have yellow bodies with black manes, tails, stockings, and dorsal stripes, as well as black manes, tails, and stockings. Duns have a dorsal stripe that is brown or dark grey, and their bodies are sandy brown or mouse grey. The color of the mane and tail varies from horse to horse. 
  • Red dun horses, as well as grulla and grullo, are affected by the dun dilution gene. Horses with chestnut coats are known as red duns, whereas horses with black bases are known as grullas. If the foundation color of a Buckskin horse is brown, the cream dilution gene causes it to turn golden. Dapples are commonly seen on the body of buckskin horses with a brown foundation color. 
  • The dun dilution gene determines the characteristics of dun horses, whereas the cream dilution gene determines the characteristics of buckskin horses.
  • Conclusion

    Buckskin and Bay Dun horses are frequently mistaken because they have several characteristics like they have the same basic color. Their coats have been diluted and are of tan color, their tail and mane being black in color.

    However, they are not identical, so we can distinguish them by looking for distinctions. There are primarily three distinctions. However, it may be hard to tell these horses apart simply by looking at them. 

    The presence of rudimentary markings indicative of a Dun horse is the most noticeable feature. However, certain non-dun horses might have rudimentary markings, making this attribute a little more difficult to spot. 

    Varied dilution genes produce different coat colors. In the case of the Dun horse, the Dun gene is present, whereas the cream gene is present in the case of the Buckskin horse. However, only DNA testing can determine this. 

    Individual hair dilution differs. On a Dun horse, the dilution is only visible on one side of the hair, but on a Buckskin horse, the dilution is visible throughout the hair. This, however, can only be seen using a microscope. In some cases, we can tell these horses are different merely by looking at them, but in others, DNA testing is required.
