HYPP traces back to a single point mutation associated with the stallion Impressive.
Since this stallion was quite popular in his day there are many individuals that trace back to him. Multiple lines of Impressive in a pedigree increase the risk of a horse
being a carrier N/H or homozygous H/H.
The AQHA has taken significant steps toward the elimination of this defect and all foals with Impressive breeding (who don't have N/N parents)must be tested for the
defect. Any foals produced who are N/H or H/H cannot be registered unless they are spayed or gelded.
While I found no specific information on the frequency of the allele in the quarter horse population, the steps being taken by the AQHA will be able to eliminate the
defect from the gene pool in a very short period of time.
Answer 2:
To add to the very good answer above , some slightly older data states that roughly 4% of the Quarter Horse population has HYPP. Another source says that it comes out to roughly 1 in 50 horses having the defect.

∙ 11y agoIt is one of the slightly more common genetic diseases found in the American Quarter horse (it can also be found in Paints, Appaloosas and any mix of these three breeds.) Roughly 1 in 50 Quarter horses will be affected by HYPP. The only way to stop the disease is to not breed any horse with HYPP.

Are horses allowed soft mints?
One or two as a treat are not going to hurt a horse provided it does not have Insulin Resistance, Cushing's (PPID), HYPP, or any other problem that would limit it's diet in regards to sugar.
What symbol would the horse breeder use to show a male who is affected by a defective gene?
There are many different symbols for horses that carry various genetic defects, it should be noted that the symbols are no different for a stallion (male) or a mare (female). Here are some examples;1. Hyperkalemic Periodic Paralysis Disease is notated as HYPP, then to show if the horse has it or not it would be listed as HYPP n/n (not a carrier), HYPP N/H (Carries one copy). HYPP H/H (carries two copies and is affected.)2.Hereditary Equine Regional Dermal Asthenia, notated as HERDA. Is listed as follows:HERDA N/N= normal not a carrier. HERDA N/HRD= carries one copy. HERDA HRD/HRD= carries two copies.3. Glycogen-Branching Enzyme Deficiency, notated as GBED. Listed as follows, n/n= not a carrier. n/GB= carries one copy. GB/GB= carries two copies.4. Polysaccharide Storage Myopathy, notated as PSSM1, Listed as follows, n/n= does not carry, n/ P1 carries one copy. P1/ P1= carries two copies.5. Malignant Hyperthermia, notated as MH, lists as follows, n/n= does not carry, n/ MH= carries one copy, MH/ MH= carries two copies.6. Frame Overo which is responsible for Lethal White Overo in foals, notated as as LWO. Listed as follows, n/n= not a carrier, n/O= carries one copy, O/O= Homozygous double carrier and lethal.There are many other genetic defects that can be tested for, but for the most part they all follow the same platform.n/n= not a carrier and safe to breed.n/ One copy= carries one copy and may or may not be safe to breed.Copy/ Copy= do not breed to this horse for any reason.
Should you exercise a horse with possum disease?
"Possum disease" is Equine Protozoal Encephalytis. It is contracted by eating feedstuffs or drinking water contaminated by possum feces. There are several treatment options including Marquis, Navigator, diclazuril and a combination of pyrimethamine and sulfadiazine marketed as Rebalance. However, Navigator is no long in production and Rebalance tends to be out of stock so vets and owners go through compounding pharmacies to have pyrimethamine and sulfadiazine compounded for use. Diclazuril has never been mass produces in a formula for treating EPM because the cost of doing so and the fact that an already effective treatment (Marquis) is on the market would likely lead to the same fate as that of Navigator---a product that doesn't sell enough to warrant production. Marquis is labelled for use for 28 days and actually kills the parasite. This product is more expensive than the Rebalance but it requires a much shorter treatment time. Marquis also has a low incidence of adverse effects. Rebalance (pyrimethamine/sufladiazine) prevents reproduction of the parasite and treatment must be continued for a minimum of 3 months to allow for the parasites that are present to all die without leaving new generations in the central nervous system of the horse. It is often recommended that this product be given for 6 months or more. Rebalance must be given on an empty stomach. About 70% of horses recover with any of these treatments. Recovery is considered a 1 grade improvement of neurological deficits as graded on the Mayhew scale 1 month after treatment ends. However, horses who are recovering from EPM can improve for more than a year after treatment. But rehabilitation must be slow and cautious for the safety of the horse and the handlers. Recovered horses also can have days when they appear to relapse and neurological symptoms reappear or worsen. This may actually be from a reinfection or it may be from an inability to compensate for neurological deficits left over from their initial infection. Horses will over time learn to compensate for neurological deficits and appear normal or at least more normal, but overwork, illness, injury, excessive heat and humidity or anything else which affects their energy level or concentration may lead to a reappearance or worsening of neurological deficits. When considering EPM as a possible cause of neurological deficits, it is very important to get an accurate diagnosis. There are many other diseases/causes that present with similar symptoms to EPM so a full physical examination and appropriate diagnostic testing including blood tests for exposure to S. neurona, x-rays of the head/neck, testing for other diseases such as West Nile Virus, Eastern Equine Encephalytis, etc.
What is best for preventing a particular genetic disorder?
Sorry bUt you answers your own question when you said genetic . Genetic disorders are in your genes given to you after " the deed is done" they are the blueprints for your body and your life the only wayyou can prevent them is by goin back in time and make your parents wait or somethin you can prevent certain diseases from progressing like diabetes or marfan syndrome bu they may still posethreats
What effect does nonrandom matinghave on the frequency of alleles in a population?
Nonrandom mating means that, for some reason, there is some selection occurring in mating, meaning that some organisms are more desirable to mate with than others. Logically, this is because of some certain characteristic or trait that is more desirable for organisms of the next generation to have. Thus, organisms with this trait or more likely to mate and produce offspring with similar characteristics, altering allele frequency so there are more of the "desirable" allele in the next generation and fewer of the "undesirable," as that allele was not passed on. For example, let's look at a hypothetical population or an imaginary animal. Let's pretend that the females are more attracted to males with brightly coloured feathers than those without pigment, and there are two alleles for the same gene that decide whether or not each organism is brightly coloured or not. Though non-random mating would mean that the allele frequency for each variation stayed the same through the generations, if more females mate with the brightly coloured males, fewer mate with the non-pigmented males. These males die without passing along the allele for non-pigmented feathers, decreasing its frequency. At the same time, the brightly coloured males pass on their allele to many offspring, effectively increasing the allele frequency. This process of choosing a more desirable trait makes rating nonrandom and changes allele frequency.
What are some of the genetic problems you might encounter during selective breeding?
um i really think that selective breeding is really wrong people thinks its funny but its really sad because selective breeding is abusing animals and maybe someone can make a illness and kill people etc. but i think its very wrong
