Buckskin is a dominant trait in horses, resulting from the interaction between the cream dilution gene and the bay base coat color. This unique coloration is characterized by a tan or gold body with black points, such as the mane, tail, and legs.
What Determines Buckskin Color in Horses?
Buckskin coloration in horses is the result of genetic interactions. The primary gene responsible is the cream dilution gene, which is dominant. When this gene is present in a single copy, it dilutes the red pigment in a bay horse’s coat to create the characteristic buckskin color.
How Does the Cream Gene Work?
The cream gene affects the coat color by diluting the base colors:
- Bay Base Color: The presence of the cream gene dilutes the red pigment in a bay horse’s coat, leading to a buckskin appearance.
- Single Cream Gene: A single copy of the cream gene results in a buckskin coat, while two copies produce a cremello.
Why is Buckskin Considered a Dominant Trait?
- Dominant Gene: The cream gene is dominant, meaning that only one copy is needed for the buckskin color to manifest.
- Inheritance: If a horse inherits the cream gene from one parent, it will display the diluted coloration associated with buckskins.
Characteristics of Buckskin Horses
Buckskin horses are known for their striking appearance. Here are some key features:
- Body Color: Tan, gold, or yellowish.
- Black Points: Mane, tail, and legs are typically black.
- Dorsal Stripe: Some buckskins may have a faint dorsal stripe, although this is more common in dun horses.
Example: Famous Buckskin Horses
- Trigger: The famous horse of cowboy star Roy Rogers was a palomino, but often mistaken for a buckskin due to similar coloration.
- Buttermilk: Dale Evans’ horse, often seen alongside Trigger, was a true buckskin.
How to Identify a Buckskin Horse?
Identifying a buckskin horse involves looking for specific visual traits:
- Golden or Tan Body: The body should be a creamy, golden color.
- Black Mane and Tail: These should be distinctly darker than the body.
- Legs: Usually black from the knees and hocks down.

| Feature | Buckskin | Palomino | Dun |
|---|---|---|---|
| Base Color | Bay | Chestnut | Bay or Black |
| Dilution Gene | Single Cream | Single Cream | Dun |
| Body Color | Tan/Gold | Gold | Sandy/Tan |
| Mane and Tail | Black | White/Light | Black or Red |

People Also Ask
What is the Difference Between Buckskin and Dun Horses?
Buckskin and dun horses may look similar, but they have different genetic bases. Buckskins result from a single cream gene on a bay base, while duns have a different dilution gene that creates a sandy or tan body with a dorsal stripe.
Can Two Non-Buckskin Horses Produce a Buckskin Foal?
Yes, two non-buckskin horses can produce a buckskin foal if both carry the cream gene. If one parent passes on the cream gene, the foal can be buckskin.
Is Buckskin a Rare Color?
Buckskin is not extremely rare, but it is less common than some other coat colors. The presence of the dominant cream gene in one parent increases the likelihood of producing a buckskin foal.
How Do You Breed for a Buckskin Horse?
To breed a buckskin horse, one of the parents should carry the cream gene. Breeding a bay horse with a horse carrying the cream gene increases the chances of producing a buckskin foal.
What is a Double Dilute Horse?
A double dilute horse has two copies of the cream gene, resulting in a very light coat color. Examples include cremello and perlino horses, which are lighter than buckskins.
Conclusion
Buckskin is a dominant trait in horses, resulting from the interaction of the cream dilution gene with a bay base coat. Recognizable by their golden body and black points, buckskins are a popular and visually striking coat color. Understanding the genetic basis of this trait can aid in intentional breeding and help horse enthusiasts identify these beautiful animals.
