Buckskin...would you suspect a white gene too?
 
I know she's Ee A? CRcr...Do you see frame or anything else? She has frosting in her mane and tail but I know that's kinda a buckskin thing. Her mom is bay (well, prolly brown) with lots of white (big blaze, three stockings and a sock) and dad is a palomino with a big ol blaze but not much if any white on his legs.
Her right fore has like a half a coronet band, her left hind has about 3/4 a little sock there.

The white goes down to her lower lip...

My best guess is that she carries a copy of a sabino gene (there are two testable mutations now). The "frosting" is not related to this though.

I would love to know what lab is testing a second sabino mutation, as I haven't heard of it yet.

As far as the OP's mare - Sabino and frame. Sabino because the face white is fairly symmetrical, and because of the way the leg white is jagged. Frame because the white is trying to spread over the eyes, and because with that much face white I would expect more leg white.

Thank you Smguidotti
And
Chiilaa I always enjoy reading your posts. I appreciate you saying exactly why you see Frame and Sabino. :-)

Dumb question: Can quarter horses have sabino and frame?

Yes, they can have sabino and frame (as well as splash, and probably dominant white, as well, though there are no tobianos in AQHA). All of the white pattern genes can hide to some degree and it's a result of these hidden genes that led to the many AQHA 'crop-outs' that had too much white to register and helped form the APHA.

Exactly!

@Chiilaa "Sabino because the face white is fairly symmetrical" This is not always true. But because it does extend to her lower lip I agree. "and because of the way the leg white is jagged" That could also be an indication of frame. "Frame because the white is trying to spread over the eyes" Sabino does this too, typically, however, in 'maximum white' specimens. "and because with that much face white I would expect more leg white," the amount of leg white is not directly related to either gene - the percent expressed is sporadic if the foal only received one copy of either gene.

But lastly, my apologies I checked my source and I read it wrong

False. Sabino does like leg white, where as frame DOES NOT put white on the legs. At all.

No, because frame does not put white on the legs.

I think you failed to understand what I wrote. I never said sabino did not produce leg white. I implied that depending on the gene is expressed could vary the amount of leg white, that sabino doesn't always look a certain way. In addition, I also have seen horses DNA tested positive for frame that had leg white. -_-

This horse could carry both genes for all we know.

She is BEAUTIFUL! In this pic she looks as if she's saying "I'm the star, this is MY photo shoot so move aside biped!"
