    Right. Im just saying that the horse colors that "appear" to be possible albinos no matter the eye color (I have even see WHITE eyes before they were so bale blue) are genetically still a modified black or bay horse under all the modifying color genes.

    Could something crop up we don't know about? Sure...But as of today, horses are never albino genetically as the definition exists.

    I don't know anything about cat colors.

    Yup I hear that. And yes, I agree, underneath it a cremello is a chestnut horse just trying to fit in

    >>>> Right. Im just saying that the horse colors that "appear" to be possible albinos no matter the eye color (I have even see WHITE eyes before they were so bale blue) are genetically still a modified black or bay horse under all the modifying color genes.

    Albinism in other species does not cancel out their other color genetic potential.

    For example I have an albino rabbit. In rabbits, albinism happens when the "C" for full color is replaced with 2 recessive "c" genes. My albino doe still has A-, B-, D-, and E- pairs of genes for color-- its just that I can't tell what they are until I breed her, because being albino masks whatever else she has. Based on her pedigree, she is most likely aa BB cc dd EE, meaning if she was not albino she would be a solid blue... who cannot produce chocolate or tort/orange.

    Rabbits have several possibilities in the "C" series-- In order of dominance, there is C, for full expression of color (just as in horses.). Then C-chd, which removes yellow pigment, (causes chinchilla when the rabbit also has an agouiti gene), C-chl which causes siamese sable (lightened body color, darker color on nose, ears, feet, and tail) and C-hi which is an incomplete albino-- the rabbit's body is white and the rabbit has red eyes, but retains color on the nose, ears, feet, and tail. Then there is c, which is a complete albino.

    Cream IS on the C series in horses. But unlike the genes on the C series in rabbits, It is an incomplete dominant-- when present with the full color C it affects the horse's color. I think in horse the pearl dilute is also on the C series? But research has never found a complete albino in horses as of yet.

    Man, I commend anyone who has the patience to learn all this stuff about genetics.

    All I read of your post Eastowest was blah blah jibberish blah....

    LOL!

    LOL sorry bout that.

    Let me try to simplify it to the main point-- albino in other species happens because of one small blip on one small part of their color genes-- they still have all the genetics to be a full normal color, and would have been that color, if that albino blip hadn't happened. They still have all the genes for whatever color they are "under" the albino to pass along to their offspring.

    In rabbits, since albinism is recessive, it takes both parents either being albino or carrying the gene for it to make albino babies.

    If both bunny parents ARE albino, all their babies will be albino. If only one parent is albino and the other parent carries it, they can have some albino babies, but also will have babies that don't get the albino from both parents, and turn out whatever colors the parents' other color genetics combine to create.

    I apologize for this (and going a little off topic)... but I couldn't resist the giggle... and to parry that with - no, underneath a cremello is a chestnut trying to stand out!

    Sabino does not cause blue eyes. The horse would have to be carrying either Splash or Frame as well.

    Sabino1 - Sabino1 Testing

    "Another distinguishing trait amongst sabinos is their eye color. They commonly have blue eyes or partially blue and brown eyes."
