What color foal do you think I will get breeding a ...?

sorrel to a black and white paint?

What color foal do you think I will get breeding a ...?
It does not matter if the dam or sire are the Paint or whatever. Color and/or Paint genetics are not sex linked.


If you are breeding to a non-homozygous Paint then you only have a 50% chance of enough white to be in the regular registry of Paints. (Homozygous means the horse has two genes of a certain trait and then MUST pass on that gene to the offspring) If the Paint is homozygous then you have 100% chance, I'm assuming this is not the case or you would have said so.


Black can be homozygous also - which does not guarantee that the offspring will be actually black, but that they will be in the black family (Bay, buckskin, brown, black, blue roan, etc) Otherwise a black horse can carry a red gene and have foals in the red colors such as a sorrel, chestnut, red roan, etc.


There are some excellent books out there on color genetics that will actually tell you what the percentage is for each color. Also, if you go onto the APHA online website, they have a genetic colorwheel that you can punch in the dam and sire's colors and see what percentage chances you have for each possible color. I believe you will have to be an APHA member to use the color wheel.


I hope that helps.

what the stud sired previously there's one in these parts burnin' love they'll just about guarantee color.


I have a paint colt (chestnut on white) that was bred out of a steel grey mare...But I knew that would be the out come
Reply:the first colt from blk.breeding stock mare and sorrel%26amp;white stud .was sorrel%26amp;wh,next one was blk%26amp;wh studcolt same parents ,but her first foal by another blk qh was dark bay .so it is not really easy to say . i would guess very dark bay or brown .50/50 on luck
Reply:It depends on the bloodlines and the dominate and and recessive traits.
Reply:The sorrel will only have red genes. RedXRed, because red is recessive. It may or may not have an agouti gene, which does not express on red horses. It limits the black coloring on black horses to the points, making bay. The paint can either be BlackXBlack, or RedXBlack (do you know the background....is either parent red? If so, guaranteed RedXBlack, but could still be RedXBlack if neither parent is red) If the paint horse contributes a red gene, then the foal will be red. If the paint horse contributes a black gene, then the foal will be black. If the red horse has an agouti gene and it is passed on, then the foal will be bay if the paint horse contributes the black gene. Definitely no agouti gene on the paint horse, or he would be bay and white, not black and white. Next....is it a tobiano paint, and is it homozygous for the tobi gene? (A simple test at UC Davis will confirm homozygous for tobi or not, as well as whether it's redXblack, or blackXblack) So, after this brief run through color genetics.....the foal could wind up red, black, or bay, and spotted or not. Is that as clear as mud? Foal will NOT be grey, as one parent has to be grey to produce a grey foal....grey is dominant. Assuming the black and white is not actually a smokey black, carrying a dilute gene you will not get palomino, perlino, or smokey black. Now, if the BW is actually a smokey....then you could get the above colors.
Reply:It depends If the Stallion is Homozygous or Heterozygous, same thing for the mare.
Reply:It all depends on whether the paint is homzyogous witht he black gene and the paint gene. If either the mare or stud is the pain and homozygous in paint and black genes then you will most likely get a black and white paint. See with a paint it's 50/50 either way yo7 go whether breeidng to 2 paints or a paint to a solid. So if the paint partner on this does not carry the homozygous gene then it's a toss up. I bred a sorrel to a black and got a bay.... bred same sorrel 4 years later to a homozygous black tobiano and got a black and white tobiano b/c he was homozygous in both genes. A homozygous black will not produce "redheads"
Reply:I have no idea. I'm thinking black and white. Sort of the pattern of a Paint. But I'm really not sure.
Reply:it depends who's who?......if the black paint is the stallion and he's homogynious ( I know that's spelled wrong) in the color black then you will most likely get a black and white paint.

Also do you have pics?
