face markings

Are certain face markings associated with certain patterns? I know white under a chin can indicate Sabino but are there others? thanks

Tobiano causes no white.

Sabino can cause just about any type of face white, though usually not bald faces.

Splash causes bald faces, and any bottom heavy white.

Frame, well that depends on who you ask. I think it causes at most a wide top heavy blaze.

Yep, what RMT said...also, Sabino tends to keep color around the eyes and splash likes to take it off.

This is how I generalize the patterns (with plenty of wiggle room)
Tobi- doesn't like face white
Splash- bottom heavy, tends to be asymmetric (like the white is off center/falling off to one side), likes to take the eyes when heavily expressed
DW/sabino- more symmetric and balanced. Avoids the eyes. Even when it takes to whole head, the eyes are still colored unless splash is thrown in the mix
Frame- Usually it wants to push another white pattern's face white to the forehead

Splash fights the KITs for the eyes (splash wants white, KIT wants color) so you can get some interesting and messy eye patterns when they are combined.

Splash is also the only one that will take the ear color (except dominant white, but DW won't cause deafness). It starts from the bottom and on the head "bottom" seems to be the upper lip or nose and a minimal may just have a snip. On the flashier ones the head can sometimes look like a normal solid horse with a straight blaze from one side and be a complete medicine hat on the other.

Sabino takes the ears as well.

That horses has blue eyes, likely multi pattern. Sabino+Splash or DW+Splash.

Nope, both his eyes are dark. He is not Dominant White, nor frame. Splash is possible I suppose, though I see nothing to be convinced of it.

He IS homozygous Sabino 1.

This stallion has tested heterozygous sabino, which he gets from his dam. His sire is a splashed white. He is also homozygous black. If sabino does not carry blue eyes, then can I assume he is a splashed white and sabino combo??

The TB is definitely dominant white based on his expression and the dominant inheritance pattern of his foals. Medicine hat is a phenotype so there is no one white pattern solely responsible for it.

Not likely. Unless they lucked out and bred him to a bunch of mares that are also carriers of the sb-1 mutation (which I am not sure is even found in TBs), then he is definitely a dominant white. Sabino-1 requires two copies to express that fully. Dominant white, on the other hand, expresses when heterozygous so that is a lot more likely. Max white sabino was the term used for that pattern until the research on DW was done and better determined the inheritance.
