The horse shown is about as "classic" splashed white as it gets. VERY interesting, looks like we're wandering down much the same path as sabino - you KNOW they've got it but the tests like to make you a liar! Loving that we're coming out with more and more tests!
The new Splash test has been very surprising. Tons of Minis have now been tested (with pictures shown on our forum) and many have tested negative for all three, when the phenotype would have told us otherwise. I am quite sure in the future, more than the present three will be mapped and made available. I hope it is not quite so many as in Sabino, however, or the cost of testing will become prohibitive.
Feathered Feet--the mini you posted a pic of DOES look frame in addition to splash...it also has some coloration in places the mare in the OP I posted does not--mainly the chest and lower neck...
The mare I posted has no "markers" visually for frame that I'm seeing. Her sire is N/N for frame and I asked about the dam--who is AQHA and doesn't "look" frame or come from known frame lines, but it could be hiding. If they reply back to me on either this mare I posted or the dams frame status, I will let you know :)
