Since all of them are revealed I'll explain the whole draft litter :)
Genetic key:
E = black (can produce black pigment)
e = red (can't produce black pigment)
Black (E) is dominant, so just ee will produce only red pigment
A = agouti, or bay, restricts black pigment to points. Only shows on horses with at least one E for the black points; if there is no black pigment, there is nothing to restrict, so ee (red) horses do not look any different no matter their agouti status
Agouti is dominant, so Aa = bay also, if at least one E is present
aa = not bay, does not restrict black pigment if present (E_/aa is the only way to get a black horse)
Any letter with a _ next to it, such as A_, means it has at least one dominant gene present and the other can test either or and not affect the color. For example, E_/A_ will always be bay, whether it tests EE/AA, Ee/AA, EE/Aa, or Ee/Aa
Each base color is used for the foals: red, black, and bay, all + roan. Yes, bay is considered a base color! It was the original color before just red or black existed, all original early wild horses were EE/AA/DD (bay dun). Only later were there red and black horses.



The first split adult outcomes revealed of each were simply the base + roan, and possibly plus a pattern.

- Red roan frame

- Black roan splash

- Bay roan solid
The other splits were meant to be sort of twists on the first ones.

- Red roan sabino. This is not roan, but a roan-like look from a sabino pattern. Extensive sabino patterns (which come from a variety of genes, some untestable, meaning we do not know the gene it comes from) can cause roan-like white ticking throughout the coat, but are caused by the pattern and not a roan gene. This is especially common in drafts like Clydesdales, where there is an untestable white spotting (a.k.a. sabino) pattern that looks roan-like.

- Black varnish, a.k.a. varnish roan. Again, this is not caused by the same roan gene but is instead caused by LP, or the appaloosa gene. It can also give a roan-like appearance but the white ticking can be a lot more wide-spread and pigmented areas can be different.
Plus, spots! Roan can have "corn spotting," which I added to every true roan outcome, but corn spotting is not an actual pattern or gene. It is caused when the horse gets a knick or cut or other injuries to the hide. The hair will grow back completely pigmented and without the white ticking. On the black varnish, however, the spots are caused by the appaloosa pattern, which is why they are in a more typical appaloosa formation rather than randomly scattered and shaped.

- Seal brown roan. Genetically, this is the same as a bay roan, just darker. There was the belief that a modification to agouti was found and that seal brown could be tested, but it isn't true. Seal browns will test exactly genetically the same as a regular bay (E_/A_). Though it is considered true that, more often than not, seal browns test EE/A_. Still, seal brown is only a phenotype. Seal brown roans can often give the appearance of being black roans. The only way to truly tell for dark seal browns, most of the time, is the "cinnamon" muzzle. I did give this one a bit more of a bay/purplish hue rather than the very close to black roan look many can have.
So there you have it! Roans with a twist. Maybe some of you found this informaton interesting :)
