The Overo allele is only lethal when the foal inherits a copy from both parents. A heterozygous foal is a normal frame overo.
Overo is a type of horse coat color pattern characterized by white markings that usually don't cross the back of the horse. It can come in various forms such as frame overo, sabino overo, and splash overo. Common base colors for overo horses include bay, chestnut, and black.
One of the main ones is OLW (overo lethal white) or LWS/LWO which occurs when two paint/pinto horses with the OLW gene both pass it to their offspring. The resulting in a white/nearly white foal that also has a defective intestinal tract and dies or is euthanized.
It is ALWAYS fatal and is the product of two overo carriers producing a HOMOZYGOUS overo. The resulting foals will not survive and can cause stress and anxiety on the mare as well as the mare owner.
There has never been a genetically verified albino horse. The albino gene does not occur in horses. There are two colors that appear albino. One is Cremello, which is caused by two copies of the gene that makes a horse palomino or buckskin. They have pink skin and blue eyes. Cremello coloration is common in many horse breeds. The other is dominant white. The horse is born white, unlike a gray horse that is born any other color and turns white with time. They have pink skin and can have blue or brown eyes. This color is a founding characteristic in the American White Horse, and the Camarillo White Horse. It is also seen in Thoroughbreds, Quarter Horses, Frederiksborg horses, Icelandics, Shetlands, and Franches Montagnes, and Peruvian Paso horses. Although, since it is a mutation it can occur in any breed or individual horse. These horses are not always necessarily completely white; they may resemble high-white sabinos in rare cases with fewer than 10% of any other coloration on their bodies - the coloration usually occurs over the topline, on the ears, in the mane, and in hoof striping. High-white sabinos, overos, and tobianos are sometimes confused for albino, even though they are not. Unlike true albinism, these horses are verifiable and reproducible genetic colors. Althought the colors are called "albino" by some people, none of these are true albinos.
The American Paint Horse Association registers only a specific line of horses that are built like the Quarter Horse but exhibit Paint markings - which are: Tobiano, Overo, and Tovero. The Pinto Horse Association registers almost any breed that exhibits these markings. They will reqister horses from Miniatures up to draft horses. The term 'pinto' is used to describe any horse exhibiting the Paint horse markings whereas a Paint horse is a horse registered with the APHA and exhibit the conformation of a stock horse.
Mostly Overo like Black overo or Bay overo
Overo is a type of horse coat color pattern characterized by white markings that usually don't cross the back of the horse. It can come in various forms such as frame overo, sabino overo, and splash overo. Common base colors for overo horses include bay, chestnut, and black.

Quarter horses are a breed, where Overo is a pattern, similar to Tobiano. "Paint" horses are considered their own breeds too. Try looking into this horse's genetics to find out more about it's blood lines. Certainly a Quarter Horse may have an Overo pattern, but so can a Paint horse.
They are usually:Rabicano, Roan, Flaxen or Fram overo.
Piebald refers to a horse that is genetically black with white spots. This means that the horse hasto be either Ee or EE at the extension site and aa (true black) at the Agouti site.This looks like aaE- (the dash indicates an allele that may or may not be known but doesn't affect the animal's appearance/phenotype) which produces a black horse.The Spotting patterns associated with the term piebald can be Tobiano, Overo, Sabino or Splashed White.Tobiano Piebald would be aaE-To-Overo Piebald would be aaE-Ovov (Frame Overo can only be Ovov as OvOv is lethal)Sabino Piebald would be aaE-Sb-Splashed White Piebald would be aaE-SW-Spotted horses can carry more than one of the spotting patterns as well since all spotting genes mentioned here are at a different gene locus.
That would be because the horse was born with the grey gene mutation. Grey horses are typically born another color and lighten gradually over time.
there are two types of paint horses overo and torbino an overo paint has more white than color a tobiano has less white an more color
they can be blue roan, red roan, black, brown, bay, chestnut, gray, sabino and overo
(pronounced: oh vair' oh)
Yes, it can. The overo color is just a color, you can find it on an Arabian, thoroughbred (Rarley) and even a quarter horse. I ride a horse that is a quarter mare, she was in nationals, and she is overo. So yes. its possible
The color of the stallion is irrelevant, however he should not be overo in order to avoid the potential for an OLW or LWO foal. The foal could be Overo , Tobiano, Tovero or solid colored.
