The Overo allele is only lethal when the foal inherits a copy from both parents. A heterozygous foal is a normal frame overo.

What is the lethal gene cambination in horses?
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.
What is the horse color overo?
An overo horse is a solid colour with splashes of white. These splashes rarely reach over the back. The opposite is tobiano, which is a white horse with coloured patches.
What is one special fact about olws?
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.
What is the horse body hair color?
There are several types of color patterns. Some examples are: tobiano overo sabino rabicano brindle
What is the rare color for a Thoroughbred?
The Thoroughbred breed has two lines that carry the creme gene. This gene can produce palomino, buckskin, smokey black, cremello and perlino. There are also sabino and overo genetics in Thoroughbreds that produce varying degrees of spotting including horses that are essentially white.In Thoroughbreds the term "roan" refers to horses with the grey gene that have a non-black base coat color. For example: a chestnut foal with the grey gene would be reported as being a roan.True roan color (horses with the Rn gene) do not exist in the United States with a report of one true roan Thoroughbred reported in New Zealand (Catch a Bird) who has offspring that are true roan.This amounts to less than a dozen true roan Thoroughbreds in the world (this number may be higher as there is no current report found).
What were the Plains Indians favorite color horses?
Mostly Overo like Black overo or Bay overo

Is a overo paint horse a quarter horse?
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.
What are the possible coat colors for Morgan horses?
They are usually:Rabicano, Roan, Flaxen or Fram overo.
What causes piebald trait in animals?
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.
Why did your black overo horse turn to a gray overo?
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.
What a paint horses looks like?
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
What colors can nokota horses be?
they can be blue roan, red roan, black, brown, bay, chestnut, gray, sabino and overo
How do you pronounce overo?
(pronounced: oh vair' oh)
What is an example of a lethal mutation?
Albinism, where the animal (or person) has no melanin (color) in their skin or hair, so they sunburn easily and are prone to skin cancer. The irises of their eyes are pink, so their eyes are sun-sensitive. Animals with no coloring of their skin can not hide from predators, so they don't live long in the wild. I don't think albinism is technically a lethal mutation. I think an example of lethal mutation is the overo gene in horses. Two copies of it produce a foal that dies shortly after birth due to problems with its digestive system. Any mutation that causes termination of pregnancy is a lethal mutation.
Can a overo horse be a quarter horse?
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
What color stud would you have to breed your tovero mare to to get an overo foal?
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.
