How do I know what color my foal will be if my Stallion is back and white Pinto and is bred with chestnut ?

If I want a black and white foal, should I be looking at a solid grey or black mare as a broodmare?

How do I know what color my foal will be if my Stallion is back and white Pinto and is bred with chestnut ?
I know that this doesn't answer the question about what color foal you will have with a pinto (heterozygous? homozygous? there is testing to find such things out.) bred with a chestnut, but it might help in figuring out the greys. :)



Each horse possesses two genes for color. One gene per horse will combine with that of the other horse, to give a foal the two color genes(with or without modifiers) it will have.



Some colors are dominant, and some are recessive. Some colors can modify an existing color (a creme gene, for instance. Or a grey.).

Grey is a dominant, modifying, gene - it has the ability to change an existing coat color to grey. A grey horse can carry one gene for this trait, or two. If it carries one gene it is known as heterozygous, if it carries both genes for the trait, it is called homozygous.



A homozygous grey will produce a grey foal 100% of the time. If the foal carries one gene for grey, that gene will dominate. It will not matter if it is the stud or the mare that has given this gene. You will have a grey baby.



Now let's say you have a grey horse that carries one gene for this color(heterozygous). It has the ability to give its dominant grey gene, too -or not. 50% of the time, then, it will pass on its gene for grey - half of the time, you will have another grey baby.



When I say "grey" baby, that might be somewhat inaccurate a picture, as the color grey will take over with the course of time - the "grey" baby may only have grey "goggles" around its eyes at first, but it will turn the other body color(the foal's base color) grey, too.



Given either of these senarios(and not knowing if you have a heterozygous or homozygous grey) you are looking at an average of 75% of the time, you will have a grey baby.



If you want a pinto foal -and want to have it stay pinto -your best bet would be to stay away from a grey!



Just thought to add this: The closer your sire and dam are(collectively) to all white, the more you could run the risk of producing a "lethal white" foal. The mare could/would carry, but the baby would not survive.

The white horses that do exist became white by genes that modified their original coat color - or are not truly all white, if examined closely.
Reply:Hmm, I am not so sure that you can tell, this is sort of like a racially mixed set of parents where the dominant color of the child is not really known until birth.



Of course if the color is not right you can have him spray painted

LOL
Reply:The only surefire way to ensure a black and white foal is to breed to a homozygous mare with the EE gene as well as the TOTO alleles for the Tobiano coat pattern.



You can't just look at the mare and your stallion to get your likely hood of color but must look at the pedigree of each and the colors of the sire/dam and grand-sire/dam and from that you can get a percentage of scenarios for color likely hood.



The other way to get what you are looking for is to find one already on the ground. Can't go wrong that way! IMO, pretty is as pretty does......

Reply:You have to look at the genetics side of things...The dominant and recessive genes,and what alleles the two horses carry,by looking at their family tree and trying to puzzle it out...It can be quite confusing!
Reply:The black %26amp; white paint has the gene for being a paint. There are two types two types of paints (overton and turbino - I think those are the terms.



I'd guess it's about 50/50 it'll be a paint. But there's a pretty good chance it'll be a chestnut paint or chestnut.
Reply:a black and white mare is what you should be looking for because that way the dominant genes for both horses will be black and white. You will have to expect some of the chestnuts to show up somewhere.
Reply:Who cares what color it is? You should love your foal no matter what. Racist!
Reply:You should see if you can get a "family tree" of your horses' ancestors. Your horses could be heterozygous, which means containing more than one trait. You could end up with a foal that isn't black, white, or chestnut. Trace the lineage and mark all the colors of the horses. See which appear most often and least, and you should be able to get a sense of the odds. When it comes down to it, unless you're using purebreds, it's all chance.
Reply:This gives some information on the inheritance of coat color in horses:

In your case, decidedly a complicated subject, because in addition to basic color, you're interested in getting spots, too!
Reply:look for a proven black and white pinto/paint mare. has your stallion had any foals? if he has chck to see if they are black and white. then he may be considered proven. breeding him to grey wont do anything. Black may but its all about the genes so look for a mare that is black and white, whos father was black and white.
Reply:Well the foul can be any color there's no telling what color it will be... who knows it might even turn-out a buckskin color! ( Because of family )

So hopefully it will be the color you want.
