    Tobiano

    This is for mustangs, yet says the same thing about he Tobiano color. It's not white on the face, just a normal marking. I would totally agree with you, if it were a white blotch on the cheek, or something odd, but this looks normal of the Tobiano to me..

    And I am saying that "normal" white is definitely caused by something genetic, and we have many tested cases where it is caused by one of the "big four" white patterning genes - tobiano, frame, splash and sabino.

    Oh, sorry, in the head pic, she had a white mark above her shoulder.

    Why can't they have just a star? Sabino is flecked coloring.. (like the horse in my pic) So, if anything, are you thinking a tovero?.. what else could It be?

    Tovero just means "tobiano and something else" so I never use that term, it is out-dated and assists in disguising a potentially lethal gene.

    How do you propose that they "have just a star" without the star being put there by some gene telling the skin to grow white hair instead of coloured? That is what it comes down to in the end.

    The horse in your picture also has frame, just looking at your avatar.

    Tobiano + Overo = Tovero. I agree, Overo horse breeding can be dangerous. The horse in my pic is a Sabino Tovero. Her father was a Tobiano, Dam was a frame Overo, and grand sire was a sabino, and she got the flecking color.. I don't know how it got a star, but then again, I thought of it as a birthmark.. except on the face.. It's not really genetics, is it? Can I breed a horse for a star?.. If so, I'll try it, but I never seen a person breed for facial markings..

    I would need to see better and more pictures to be able to see if tobiano is present. Looking at the picture in your avatar, which is small and blurred, I can't see what patterns are present except for frame, sabino and maybe splash.

    All things that affect coloring, no matter what the species is, has genetic causes.

Some of these horses don't have any Paint or pinto-colored horses in their bloodlines.
    And no doubt there. But you forget the mention the other side - there are horses with markings that do NOT test positive for any known pattern gene.
    To get really technically: yes, there is probably a gene, probably more than one, that creates markings. But why would you want to call that gene a pattern gene? That is a wording that is used to descrobe painted horses - pinto pattern of all kinds, not a solid horse with a star. I own two tobianos - one has sabino in him, I agree (white spots underneath his head). The other one has a small star and stripe - I just refuse to call him a "Tovero" because of that!
