1 ] The framework allele is associated with deadly whites, the other genes, such as e.g. ponies with swabino and split-allels, are not. There' s a hereditary connection between split whiteness and numbness, but the connection is not yet fully known. Framed overo' have sharp, uneven, horizontally aligned whites.
Like here, they are often bare and whitish spots rarely crossing the top line and form a "frame" of non-white fur. Specifically, the framework overo gen can be masking by other knows pattern, especially tobacco, which is a dominating gen and epistato to overo. 5 ] Epistatically means that when both are present, this is the one that is express.
Organisations such as the APA recommend that all types of horse with exaggerated pedigrees should be checked for wear before breeding. We have a genetic test for the genes, with which we can design the breeding and prevent the production of affected colts.
2 ] The malformation was not found in monochrome thoroughbred ponies without pattern. 5 ] A diseased filly who happens to be caucasian can also be checked to prevent unintentional euthanasia of a non-lethal colt with a single cock. Fatal offspring should not be mistaken for genetic whites, not even "fully developed" whites, each of which can also be entirely whitish with pinks.
Blueyed, rose-coloured creamless stallions and other horses bearing the creme genes do not wear the lumbar spine allele unless they also have an Overo genetically engineered forefather. There is no association of split whites and sabinos, although such a horse can also be a carrier of the allium. In the non-U.S., the word "splash" is sometimes used for a horse with an apparently Sebino pattern.
The pinto spotspotting pattern of a Smooth Horse shows Overo' s and Tobiano' s traits and probably bears traits for both. An example might be a smooth-edged tabloid torso with a round edge and clear back, but with uneven features and blueback. Equine animals can also have a mixture of frames overo and lead to patters that are hard to place in a group.
"There is a misense gene variant in the end-othelin blockers associated with Lathal Whitefoal Syndrome: a horse variant of Hirschsprung's ischemia.

There is no real albinomutation of the colour genes in the horse, although several types of purebred horse are commonly referred to as Albinus.
