Question Frame Overos...?

I know whet a frame loooks like, but other then that, I'm stupid.

Are frames a bad sort of thing? Why is it a rule to never cross 2 frame overos? What exactly makes a horse a frame?

I know, I am an idiot. But I've just never really known much about the color. Thank you to those with enough patience to seal with me :) Learn something new every day!

No, frame isn't bad. A frame horse will have a body of solid color, but the face, legs will be white. The reason you can't breed two frame overos is because they may create a foal called a lethal white. A lethal white is born under developed, I think something to do with organs not developing? The foal will either be born still born or will die shortly after birth. This has something to do with the chromosomes I believe? I'm not a breeder, so I'm not completely sure I'm correct.

Thank you! I feel smarter :p Yes, I've heard of lethal whites, but never knew how to get them, per say. Thanks!

Frame doesn't put white on the legs and leave the body coloured. It leaves the legs coloured as much as possible. The white will be on the body, neck and head, and will spread horizontally along the horse. It will try to avoid crossing the horse's spine as well as touching the horse's legs.

Frame is a dominant gene, so to display it only needs one copy of the gene. This makes horses with frame N/O. When you breed two N/O horses together, there is a 25% chance that the foal will be O/O. This foal will die a slow painful death unless a vet is there to put them to sleep. Essentially the digestive organs don't form completely, and there is nothing that can be done.

Frame is also known for "hiding," meaning it can make very minimal markings, if any. Hence why you will see testing for it brought up in many breeding threads.

My mare is solid and tested N/O.

Let's be real, the small spot by her elbow goes completely unnoticed by everyone. And her blaze is only a giveaway to nerdy color people like us.
