Sootiness is believed to be an inherited trait involving multiple genes, however the details are not yet known. Horses without any visible sooty coloration are termed "clear-coated." On bay -based horses, the most common type of sooty is black countershading.

In Horse Reality, the sooty gene is responsible for causing the darkening of the coat. The dominance of the sooty-alleles (STY, sty), however, differs between breeds and sometimes even between coat colours. Sooty may be a dominant trait on bay bases, for example, while being recessive on chestnut bases.

Nov 28, 2022 · What Is The Sooty Gene In Horses? Published by Henry Stone on November 28, 2022 A horse coat color that has the sooty trait is characterized by black or darker hairs mixed into a horse’s coat, typically concentrated along the …

Because cream gene has very little effect on black hairs in its single state, smoky black is very hard to distinguish from brown or (very sooty) dark bays. Often the best way to tell if the horse carries the cream gene is to have it genetically tested.

Sooty: Sooty is a common color modifier that can act on both red and black based coats. Sooty, also known as smutty or countershading, causes dark hairs to be spread throughout a horses coat, usually concentrated from the top of the back down.

Jun 24, 2019 · A characteristic that often affects palominos and buckskins (but can affect many other colors) is the “ sooty ” or “smutty” coloration. Soot appears to have a genetic component, but it has not been genetically mapped yet.

Thought to be a form of natural camouflage, the sooty or smutty gene causes black hairs to grow mixed into the body coat, generally concentrated along the topline and points. This often results in counter shading, dappling and in rarer cases brindle or dun type striping.

Nov 28, 2022 · Sooty horses have a genetic modification resulting in a horse that looks like soot has been dumped over him, i.e., darker on top and lighter underneath. These are the darkest of this color breed. What is a sooty palomino?

The sooty trait is responsible for many dark bays and has a particularly pronounced effect on buckskins and palominos. Although this trait has been called the "sooty gene", similar coat-darkening conditions studied in mice suggest that coat darkening is a polygenic trait.

Aug 4, 2015 · Le gène Sooty (aussi appelé « fumé » ou « charbonné » en France) est noté STY quand l’allèle est présent et sty quand il est absent.
