Appaloosa varnish is a progressive silvering effect that leaves colour (called varnish marks) on the bony prominences of the face, lower neck, forearm, knees, hips and stifle. It is caused by the SvS allele. This is probably semi-dominant: it's thought that horses homozygous for the allele become lighter than heterozygotes. Varnish roan is thought to occur due a single, simple dominant gene on equine chromosome 1 (ECA1). [1] It also appears that specific white patterning genes produce the assorted blanket, leopard, and snowflake coat patterns. [2] Without these white patterning factors, horses with one or two copies of the dominant Lp gene are "varnish roans."

The varying types of roan patterns are sometimes referred to as frost, varnish roan and frosty roan. Solid There are some Appaloosas that have no spots or roaning at all. This may seem contradictory, but an Appaloosa can be solid-colored. Appaloosa roan / Varnish roan / Marble This is a distinct version of the leopard complex, and is characterized by: Intermixed dark and light hairs. A lighter color on the forehead, jowls and frontal bones of the face. A lighter color on the back, loin and hips. In some horses, darker areas appear along the edges of the frontal bones of the face. Varnish Roan When a horse carries at least one LP allele but no pattern modifiers, we get the most basic possible appaloosa pattern. This is called "varnish roan". Varnish roans typically begin life with either a very small amount of white roaning in the region of their hindquarters and/or face or no white at all. Without a pattern, leopard complex is varnish roan. If the horse also inherits the right kind of patterning gene (or genes), like the elderly gelding Comanche above, he will be a blanket appaloosa. Genetically Comanche is still a varnish roan, but the pattern gene he inherited transformed the varnish pattern into a blanket.

What It Takes To Be An Appy. The Appaloosa Horse Club (ApHC) recognizes 13 base coat colors: bay, dark bay/brown, black, buckskin, grulla, dun, palomino, cremello/perlino, chestnut, gray, bay roan, blue roan, and red roan. The following are representations of each color, reprinted by permission from the ApHC, with the exception of the Cremello. Remember the varnish roan from a few days ago? His pale hooves suggest he's probably homozygous for Leopard Complex. He doesn't have a pattern gene, so there are no spots to remove, but his hooves are a clue. Here is an elderly fewspot leopard with the same kind of coloring on his hooves. They aren't completely without stripes. The Appaloosa is an American horse breed best known for its colorful spotted coat pattern. There is a wide range of body types within the breed, stemming from the influence of multiple breeds of horses throughout its history.. Horses with the varnish roan and snowflake patterns are especially prone to show very little color pattern at birth. Appaloosa is a gene that causes spotted patterning on a horse's coat. Defined by it's presentation of mottled skin around the eyes, muzzle, flank and genitals, and loud, flashy coat patterns, Appaloosa is a unique marking that presents with several different options. Striped hooves and white sclera are hallmarks of the Appaloosa pattern.

A phenomenon that somehow belongs to the Appaloosa is the Varnish Roan. There are hardly any horses that don't have it. It is not to be confused with the normal prickly hairiness found in other breeds. The difference can be seen in the fact that the heads and legs of the "normal Roan" remain dark. The Leopard Complex has several distinct basic patterns: spotted blanket, snowcap blanket, leopard, few-spot leopard, varnish roan, snowflake, frosted and mottled. These patterns can occur in isolation, but it is also common for horses to have combinations of two or more of the basic patterns within the Leopard Complex group.
A varnish roan is an appaloosa trait, and it roans out the WHOLE BODY, unlike standard roan, leaving color on just the hard points (shoulder, facial bones, etc.) and occasionally leaves underlying spots solid. Common areas where Varnish Marks are found are over the bridge of the nose, above eyes (giving the appearance of eyebrows), also on the point of hip, behind the elbow, on the gaskin and stifle region. The presence of Varnish Marks aids in determining whether a horse is a Marble pattern Appaloosa or simply a roan colored horse. Face/Leg Marks

The Appaloosa is one of the oldest American breeds - it was developed by the indigenous Nez Perce people. These horses are characterized by a distinctive spotted coat, but there's much more to the "Appy" than just their unique markings. Here are 19 things you might not know about the rugged Appaloosa horse. Table of Contents 1. A varnish roan on an Appaloosa horse typically develops on the hips and loin, with white or dark spots on the skin. It may also develop on the forehead, jowls, and frontal bones. Some Varnish roans are also absent or only have a few tiny spots. Usually, it develops gradually over the horse's life.
