I know this might sound like a dumb question but I want to confirm my thoughts on this.
I have a bay belgian warmblood mare with a white sock and blaze, I am breeding her to a CSH Stallion who is a solid bay with no white. There is no chance of frame there is there?
Yes frame doesn't always have a physical characteristic that can be seen. Which has to do with dominance of genes and such. It's like when people carry genetic diseases or defects that they themselves don't have due to the masking effects of dominant genes over recessive ones but some of thier children inherit the recessive gene/genes and are afflicted the the disease or defect.

Now just so you know horses who are born almost completely white may not be lethal white foals, there are max sabino and dominant white horses who are born almost completly white that of course have no problems, though these horse can carry a frame gene. My gelding is an example of a genetically non grey almost completely white horse. He's my APHA paint Pepper Sonnys Butch Cassidy Paint if your interested in his breeding. He is registered as a chestnut Overo but his coat pattern is definitely max sabino but that is an "Overo" pattern. Besides some red ticking on his ears, neck, shoulders, hind quarters, and some red hairs in his mane and tail the rest of him is white. So he is almost all pink skinned except for areas of black mottled skin pigmentation where the red ticking is. Now if in some theoretical situation where I wanted to maybe breed him (can't actually he is gelded and not stud material anyways) I would definitely have him tested for Frame. Even though neither of his eyes are blue I know for certain that his mother is a probably a frame carrier because of her one blue eye and the white pattern in her face. I wish I had a picture of her but I don't. Then there is pepper's sire who is a loud chestnut overo, I don't know his Frame status though but he comes from a long line of known "overo" carrying horses even though they are registered AQHA you can see from allbreed he has Sonny Dee Bar close on both sides of the family, so there is a possibility of him being frame. Sonny Dee Bar was known for having "Overo" (i hate that term) white patterns I believe the exact ones are splash and sabino not sure about frame. Feel free to enlighten me on that someone. Anyways with so much "overo" in his backround not just Sonny this gives pepper the possibily of being frame even though I can't see it.
As I was typing this I came up with a question to ask! I'd love someone to educate me! Now when Pepper was young he was a classic medicine hat paint and his ears have the most concentration of color on his body even today though there is a lot of white enterdispersed on his ears but the inside of his shows the true red with no white hairs. Anyways my question is what causes the Medicine Hat marking is it associated with Frame or multiple patterns together?
Peppy, it's usually multiple genes working together. Most have tobiano with some combination of frame, splash, and sabino. But some don't have tobiano. Something like homozygous splash and frame loud enough could cause a medicine hat. Meh. Just throwing things out there.
My mare foaled a perfectly normal foal, and the next time, she gave birth to a lethal white foal from the same stud. She had an emergency c-section and hasn't been bred since. It is to bad because her one foal is awesome and she has such a great mind!
