A Red based horse with no black gene and no dilution gene with black pigment in skin, but red pigment in hair. A sorrel/chestnut horse that received one copy of the crème dilution gene from its parents, giving it a coat ranging in color from pale cream, to golden, to chocolate and has a white mane and tail. A sorrel/chestnut horse that received one copy of the crème gene from both of its parents, and has pink skin, blue eyes, cream to nearly white hair coat, and a white mane and tail. 4093 Lake Avenue, Burdett, N.Y. 14818 PaintedBarrStables@gmail.com www.PaintedBarrStables.blogspot.com PAINTED BARR STABLES Dun Genetics Horse shows a diluted body color to pinkish-red, yellow-red, yellow or mouse gray and has dark points including dorsal stripe, shoulder stripe and leg barring.
Duns MUST have the following characteristics: Black or brown leg; The head will be darker than the body; Dark tips on the ears; A very DISTINCT dorsal stripe that runs fully from the base of the mane and into the tail.
Duns will often have other characteristics such as: Stripes on the legs (leg bars); Mottling on the upper legs, shoulders, gaskins; Dark rings around the ears; Striping on the forehead (cobwebbing); Stripes crossing the back, shoulders, or neck.
This dun gene acts similarly to the crème gene in that it dilutes the base color, but not quite the same. Black Blue Dun, Mouse Dun or Grullo A Black based horse with no “bay” gene, and no dilution gene, ranging from “true” black to brown in appearance. A black horse with the dun gene.
Grullos range in color from light silvery-white to dark chocolate brown, and some almost look black. Bay Classic Dun A Black based horse with the “bay” Agouti gene, which restricts the black to the mane, tail and legs (also called black “points”) and no dilution gene. Sorrel/Chestnut A bay horse with the dun gene.
Classic Duns are usually a yellow or tan color with dark points but can be as dark as a typical bay. Red Dun A Red based horse with no black gene and no dilution gene with black pigment in skin, but red pigment in hair. A chestnut or sorrel horse with the dun gene.
Red Duns are red in color and sometimes diluted to a very light red.
The dorsal and dun marks are usually a dark, undiluted red color. 4093 Lake Avenue, Burdett, N.Y. 14818 PaintedBarrStables@gmail.com www.PaintedBarrStables.blogspot.com PAINTED BARR STABLES Gray Genetics The gray gene (G) is an autosomal dominant gene. A horse which has one copy of the gray gene, even if it has a gene for another coloring, will always become gray.
Horses with the gray gene show progressive silvering with age to white or flea-bitten, but is born a non-gray color.
Pigment is always present in skin and eyes at all stages of silvering.
While gray is visually a distinct coat color, it is genetically a pattern that is imposed over other colors.
Horses are not just ‘gray’; they can be bay grays, cremello grays, silver grullo roan grays, etc. Early Signs of Graying White Gray Early graying signs: gray shows first around the eyes and backs of the ears.
The face turns light, too, which is not seen on roans (which these foals are often mistaken for) Rose Gray A horses who has completed the graying process.
All pigment in the hair, including that in his mane, tail and legs has been removed.
The darkness of the muzzle is just the skin. Steel Gray and Iron Gray Early Stage of Rose Gray — Ch ch Prl Prl prl F F f Dun Gene: Another dilution gene.
DD or Dd: Horse shows a diluted body color to pinkish-red, yellow-red, yellow or mouse gray and has dark points including dorsal stripe, shoulder stripe and leg barring.
Dd: Horse has undiluted coat color.
Tobiano: a form of pinto patterning.
TOTO or Toto: Produces regular and distinct ovals or rounded patterns of white and color with a somewhat vertical orientation.
White extends across the back, down the legs, but face and tail are usually dark.
Toto: No tobiano pattern present.
Overo or Frame Overo pattern OO or Oo: Pinto horse pattern that forms a solid frame around white spotting.
White is usually horizontal in orientation with jagged edges, color crosses the back and legs, face is often white.
Overo as an allele is different from overo as a registration since the registration also includes the splash overo and sabino alleles.
Homozygous overo is associated with lethal white syndrome, characterized by an incomplete colon and the inability to defecate, which leads to death or humane euthanization within days of birth.
Oo: No overo pattern present.
Champagne: A rare but dominant dilution gene that creates pumpkin-colored freckled skin, amber, greenish, or blue eyes, and gives a bronze cast to hair.
The skin surrounding the eye must be pink with freckles in adulthood.
ChCh or Chch: Champagne dilution evident (See Genetic Formulas Chart below.) chch: No champagne dilution  Pearl: A new rare recessive dilution gene that looks very much like Champagne.
The Pearl gene is sometimes referred to as the “barlink factor.” One dose of the mutation does not change the coat color of black, bay or chestnut horses.
Two doses on a chestnut background produce a pale, uniform apricot color of body hair, mane and tail.
Skin coloration is also pale.
Pearl is known to interact with Cream dilution to produce pseudo-double Cream dilute phenotypes including pale skin and blue/green eyes.
PrlPrl or Prlprl: No pearl dilution.
Prlprl: Pearl dilution evident.  Flaxen: Effects visible on red or chestnut colors only.
FF or Ff: Red points on ee horses.
Ff: Flaxen points on ee horses.

Appaloosa or Leopard spotting gene.
Produces coat spotting patterns, mottling over otherwise dark skin, striped hooves and white sclera around the eye. 4093 Lake Avenue, Burdett, N.Y. 14818 PaintedBarrStables@gmail.com www.PaintedBarrStables.blogspot.com PAINTED BARR STABLES Partial list of Genetic Formulas and Color Definitions Chart based on Dr.
