    My black and white tobi is roany on his sides so he looks all smudged. Not that you could really tell with all the mud ... :(
    Awe, thank you! Those pics are really old, from the summer that I rescued her. I am on a different computer since mine is shot right now so I haven't had the chance to upload any recent pics. She has gained about 200# and is a bit more filled out...she is a cutie :) I will try to get some added in the next few days. Your guy sounds like a cutie. Roaned sides? Sounds interesting!

    I have not...when we bought her she already had the test papers they just came long with I am curious haha. I would have to check, but I know that somewhere on them it says something about she will pass black and bay based horses but no reds. Is that what you mean? They possibly checked for both *pulls out binder* I will have to double check. If that is the case, does it change the genetic possibilities as far as color again goes for the foal?

    It does change them slightly if you know.

    Can't be homozygous agouti if he sired blacks and grullas. Agouti would turn them into bays and bay duns.

    Okay, so I've narrowed it down and have a possible breeding to Mr Zippo Pine this Spring. He is a chestnut 15.2hh stallion ... with my 14.3hh black homozygous mare ... would that lead to the same possibilities that were given on here previously?

    I don't know the genetics of Mr Zippo Pine (as in, if he carries Agouti or Silver or not), but if your mare is homozygous for tobiano and black, you're looking at 50% black tobiano and 50% bay tobiano.

    Hmm...something to think about. Thanks!
