    I don't believe she's dun. She shows exactly the way my countershade mare does. I see no zebra marks. Her ear tips are the right size..it may just be the crappy photos but I don't see dun.

    Please do not jump on me for official AQHA colors as I do know that horses are not always correctly registered, but this is what AQHA has:

    This mare here is registered as a dun.
    Her two foals that I could find on allbreed are registered with AQHA as dun (by a dun sire) and a bay roan (by a bay roan sire) - that is not very helpful

    If a horse has more than one color modifier (like roan, dun, cream, ...) AQHA will register only with one and maybe mention a second or third modifier in the description. This mare could be a dun roan, yet registered as a dun. Her sire is a grullo, her dam a bay roan. Why/where somebody came up with "buckskin" in allbreed - who knows.

    Again - all this information is from AQHA and should be taken with a pinch of salt

    I, personally, tend to call her a dun roan from the pictures.

    The way you can tell this mare is dun even from the crappy photos is three things. One the dorsal is sharp and crisp, two the very prominent masking a dun characteristic and three the hue of her coat. Defintily a bay or brown dun as for the roan not sure since she only looks roany in the first pic. Definitely need better pics.

    EDIT: actually I'm going to go ahead and call her roan because of the pointed black on her legs.

    So dun, roan, or dun roan? Is that possible?

    Also, if I was to buy her, is there a place I can send hair for dna mapping to tell me what she is?

    Yes a horse can be dun and roan which I'm pretty sure this mare is.

    So does Dun have a base colour too? Could she be a brown dun roan? Or Dun Brown Roan, or... I thought I paid attention in High School Genetics class but I guess not enough ;)

    Dun is a modifier. Every color is a modification of one of two base colors (red and black).

    A bay dun roan would be Black base + bay agouti + dun + roan.

    A brown dun roan would be Black base + brown agouti + dun + roan.

    Crazy. Next someone will tell me she can produce brindle babies! Wouldn't that be nice...

    Hypothetically breeding her, what do you think could be the craziest colour she could produce?

    UC Davis can do all those tests, except brown. (They offer an agouti test, but it does not differentiate between bay and brown) Currently PetDNA is the only lab that tests for brown agouti.

    You'd probably want to test for Comprehensive Agouti through PetDNA, and Dun and Roan through UC Davis if those aren't obvious when you see her in person (you might still want to test to find out zygosity, depending on how curious you are)

    If there's a possibility you might breed her, you would definitely want to test for Lethal White Overo (because Frame can hide even on horses that have no white markings!), and possibly for Red Factor (she clearly has at least one black allele, but could be homozygous or heterozygous)
