Non-Seal Based Genes
Mink- [Mnkmnk] A modifier
Fox- [Fxfx] A dunlike modifier gene
Puffin- [Pufpuf] Black based coats only (doesn't appear on chestnuts) Results in a splashlike pattern and darkens bay coats to nearly black, can sometimes result in orange facial markings
Caribou- [Carcar] Makes a horse's coat look like a caribou's, only appears on chestnuts
Seal Based Genes
Hooded seal color gene
HoHo (Ee/Atat base modifier; only expresses on seal bay)
Bearded seal color gene
Bdbd (only expressed on black horses- sometimes mistaken for grey, genetic testing is needed)
Grey seal color gene
Gsgs (sometimes mistaken for Appaloosa)
Ribbon seal color gene
Riri
Leopard seal color gene
Lele (expresses on black)
Weddell seal color gene
Wdwd
Crabeater seal color gene
Cbcb (often mistakes as grey, genetic testing is needed)
Elephant seal color gene
Elel (sometimes mistaken for bay dun, but lacks primitive markings)
Monk seal color gene
