would this breeding cause a lethal white??
 
I have a red roan paint mare, she is registered "overo" She is all roan with a bald face and 3 high socks. I was interested in breeding her to a stallion with similar lines and he to is registered "overo" he is also solid- (dunskin with a bald face and blue eyes) would this breeding result in a lethal? I don't know much about breeding paints and am trying to find any information I can!! thank you in advance for any help you can give!!

Easily if they're not tested. The blue eyes and "solid" appearance indicates that the stud is splash, but bald faces and high whites can just as easily be frame and a LOT of horses carry both splash and frame.

The only possible way to prevent a lethal white would be to have them tested for frame - they both have to carry frame for it to happen. If only one is frame, then you're fine.

MM your right for the most part. The only thing that is wrong is frame does not cause leg white. If anything it inhibits it.

Even if the horses weren't registered "overo" and had no white markings, if they come from Paint lines, they should be tested. The frame gene doesn't always "come through" phenotypically, and I've heard of tobiano to tobiano (or solid to solid) matings that produced lethal foals. So not worth the risk.

My last foal was a lethal white, I did not get them tested. The dam was a solid black appaloosa. No white. The sire was a solid chestnut. The man with the stallion said that the stud was tested, but apparently not. And I lost the foal. I would do it, its not worth losing one.

thanks everyone!! I will contact the breeder to see if he's been tested first. I'm very iffy about the breeding, they would make an awesome foal but I couldn't stand to loose a foal!!

Excuse my ignorance, but could someone please explain what lethal white is?

It's a cheap test, so if you don't end up breeding to that stallion, you can at least know for the future. I plan on testing my mare, more out of curiosity than for breeding purposes. Her dam was an overo, but she came out solid...or so she appears. :P

Drummerboy, Lethal White is a condition that happens when two horses that are carriers of Frame Overo. It causes the foal to have a improperly developed colon. The foal is born stark white and usually dies within 72 hours painfully. They are usually euthanized immediately after identification to spare it suffering.

The foal doesn't have to be stark white to be a lethal. A majority of lethals are all white, or mostly white.
