This is just my two-cents but almost every gene that causes white has the potential to pop up in every breed -- species -- especially when people selectively breed/line breed animals.

Look up the term "leucistic" for some bizarre pure "white" animals -- also related to 'pie-baldism'. Some leucistic dear resemble sabino patterns seen in horses, it's quite interesting.

The same pattern anomaly can be seen with snakes and other reptiles too.

I'm NOT saying all the genes are the same but just suggesting that what ever causes these phenomena could be related is some very minuscule way

Have you tried to find any information on the apparently splash NZ Thoroughbred named Hey What The and her foals Bubba and Whatever? All three have (or had...Bubba was euthe'd in '08) completely white faces (Whatever has two blue eyes), white bottom-half of the tail, and stockings. I'm currently trying to find if there has been any kind of testing done on them.

It's so very interesting.

No. The only stuff I found in a few second Google search was from a TB color breeder who used to be a member here showing off pictures of one she assumed to be splash, but it was in 2008 and the splash test was only released to the public last year.

It would be interesting to see if they get tested now and what comes back. Whatever their genetics are, they are gorgeous.

Green Broke
This is one of my mares. I see varnish roan (obviously lol) and a blanket with some spots. Does anyone see anything else?

She's a LOT fatter now. Lol.

Would it not have a 50/50 chance of producing a foal with the appy trait?

Am I missing something?
You are correct - I hurriedly typed 25% instead of 50%...duh.

Two colored Appys will yield 25% solid, 50% colored, and 25% homozygous colored.

A colored Appy and a solid horse will yield 50% colored, and 50% solid, and of course 0% homozygous.

He is a snowcap correct? Is there something else at play causing his spottiness in the other areas?

Historically, the only way to confirm a snowcap is to cross them with solid horses and get color 100% of the time, because there are both false snowcaps and false fewspots. Mares don't produce enough foals to know for sure, so confirmation was primarily confined to stallions. With the new Lp tests, homozygosity may be able to be determined - I'm not sure because I honestly haven't reviewed all the tings they can now determine with the new tests...

I don't really have anything too scientific to add to this, but is anyone familiar with the AQHA registered stallion Reminic In Spots? Both of his parents are AQHA and passed on the gene to him. Apparently with changes to rules regarding white on Quarter Horses he was allowed to be fully registered. More info on him can be found here. Figured since we were sort of on the subject I might as well throw him in here for discussion.

Yes, Reminic comes up often. Don't believe everything you hear about him - he is the result of a fencejumper somewhere along the line...
