WOAH!!!! SCARY-looking horse!!

Also noticed that Impressive is rather Inbred...

I've been doing research for the past couple of hours and have put together my own image reference guide to the current day top stallions with Impressive in their pedigrees.

The HYPP gene has been traced back to Impressive; HIS was a mutation which he passed on to his descendants. I think (I'm sure someone will put me right if I'm mistaken) that the TB genepool is smaller than that of the QH and yet no HYPP.... so I'm not sure it's correct to say it's the result of inbreeding. Absolutely no reason to propagate it deliberately though!

having read this post and looking at the horse i cant belive people breed these horses ditto all comments

.. if you google impressive a site comes up with him and at the bottom a whole load of stuff on hypp i have just read the "experiences" and was very near to tears at what people have witnessed of these horses.. it also did have a petition but it was for 2006 so fingers crossed something will be done
 
They did, at one point, try to make a link to Three Bars and use him as the scapegoat in all of this, however I don't think there was any proof that there was anything wrong with him, just the fact that Impressive had been inbred with him in his pedigree a few times.

Recent findings have categorically proved that it is only Impressive who had this mutation - no real reasons have ever been brought to light as to why HYPP surfaced though - it's a bit of a mystery.

I don't know much but am assuming that this is a "halter" horse. There is BIG money in showing in USA and that means breeding to extremes in some cases...

In my opinion these type of halter horses are disgusting and owners should be shot but that is never going to happen and no doubt it will slowly but surely creep into our show circuit too...


He's probably crippled because, apart from all the muscles etc, they trim their feet so they are totally tiny and therefore it makes their forearms and muscles look even bigger.

It's absolutely disgusting but is the "norm" apparently on the show scene over there. I've heard some of the horrors that they do to Pleasure horses; not very pleasurable...

The fact that this horse has won so many points etc says it all, horses that look like that win and so that is what people are going to keep doing and pushing the breed type to the limit.

it already has - you only need to look at welshies......
 
Impressive is half thoroughbred, so it could make sense?

"The original genetic defect causing HYPP was a natural mutation that occurred as part of the evolutionary process. The majority of such mutations, which are constantly occurring, are not compatible with survival. However, the genetic mutation causing HYPP produced a functional, yet altered, sodium ion channel. This gene mutation is not a product of inbreeding. The gene mutation causing HYPP inadvertently became widespread when breeders sought to produce horses with heavy musculature. "

Why could it not have been due to inbreeding in the first place? I was only researching about the cause of the condition in the first place. Inbreeding causes many conditions, so why should it not cause this genetic defect?

What is this " hereditary equine regional dermal asthenia (HERDA) which is carried through the Poco Bueno line"

Sorry, bit off topic. Never heard of it before and thought the Poco Bueno line was a good one?

He was a good one, but horses suffering from this have been linebred somewhere. Both sire and dam have to be a carrier to pass this awful disease on.

P.S. Regarding the halter horses, I also agree that they are grotesque and are certainly not capable of being a working horse which is what a quarter horse was originally bred for.

As shown, problems with linebreeding do not always show up until it is too late. Poco Bueno was born in 1944 and Impressive in 1969.

Please, lets stop breeding mares to their fathers and grandfathers - surely we have enough other stallions to breed from.

I really do not get the point of Halter horses. But then again I don't get the point of anything to do with horses that doesn't at least eventually involve riding or driving them.

HYPP is a genetic disease derived from a mutation that causes massive muscle bulk but also has some very serious negative effects up to an including death. A "N/H" horse is heterozygous for the disease, meaning it got the mutated gene from one parent, and will likely have symptoms but not at their most cripplingly severe. Such a horse used for breeding (WHY!?!?!) has a 50% chance of passing on the gene. "H/H" horses have two sets of the gene and will be more severely affected. If used for breeding (which is actually not endorsed by the AQHA anymore) they will for sure pass on the "bad" gene. Horses from the originator of the disease, Impressive, have to be checked and their status marked on their papers. Horses that are "H/H" can be related to Impressive but do not carry the gene.

Honestly, the whole debacle over this disease (or any other of the equine genetic diseases) disgusts me. Why breed a "defective" horse? Just to win a ribbon? No concern about the quality of its life? There are many H/N stallions standing and I just can't see how anyone consciences even taking the chance of bringing another afflicted horse/carrier into the world. Yes, breeding to a N/N horse means the foal MIGHT only be H/N and the disease can be managed somewhat, but honestly . . .

Genetic disease don't "come" from inbreeding, although they are propagated by it. Mutations occur all the time and usually they pass unnoticed because they a) don't convey an advantage and b) don't continue on because if the "mutant" mates it will not likely do so with some random animal with exactly the same mutation. In this case, though, the mutation that causes the disease also caused a very desirable result which meant it not only stayed in the gene pool but was actively encouraged by inbreeding. By the time horses began to keel over in noticeable numbers and genetic testing was available to find out why the damn horse had something like 10,000 descendants!! (Might be 40,000 - I'm doing this off the top of my head - but that seems extreme.) What amazes me is after all the drama people are still making more of them!
 
gross. absolutely minging. is it the HYPP disease thing that makes him look that way or is her overweight aswell? it seems hard to tell he doesnt look like a horse at all.

i would write my thoughts of them promoting his disease on their guestbook but cant find it on their website
