Gene
The genetics behind sooty haven't been discovered yet.
In our game, Horse Reality, sooty is caused by the sty-allele of the hidden sooty gene. This allele acts recessive on chestnut bases, and dominant on bay bases. For any color we don't know the genetics of yet, we have to come up with something to make it work in-game. Which means working with just observations and theories. Since sooty isn't testable yet in real life, it also isn't testable in game.
Presence in horses
Sooty is common and present in most horse breeds.
