Question about inbreeding...

So I was looking at the pedigree of one of the horses I ride at the barn, and I noticed that her parents were half brothers/sisters and their parents were half bros/sisters. Is that considered inbreeding? Couldn't that lead to problems in horses?

I would say it :)

Some people might call it line breeding though, I've never had anything like that, nor do I want to have anything bred like that.

I think that's called line-breeding, although brothers and sisters, even half are pretty close...

My baby is a great-grandson to Impressive on mama's side and a great-great grandson on daddy's side...

That's normal Farmpony, you see lots of that. Remedy, my horse, is a great-great granduaghter of Colonel Freckles on both the top and bottom, but that is spaced so far apart. Same as your guy.

Yeah half/brother/sister... I'm not sure, that's awful close.

Thanks guys. She's be bred to a quarter horse stud, hopefully she isn't related to HIM too lol.

It's common, but it can still lead to problems. In Standardbreds, you are seeing so many line-bred horses that are showing abnormalities. The most common is small, mismatched feet, or deformed feet. NOT good in any horse, but especially a racehorse.
In QH's, isn't that where the HYPP problems with Impressive came from? Was he super line - bred? BTW, I LOVE Impressive horses, I don't want to bash them! Way back I had a daughter of impressive, and she was a great horse.

The theory to line/inbreed is to duplicate exceptional qualities; conformation, attitude, even color but with every good quality duplicated there is also a flaw being duplicated as well.. for example a picture perfect stallion exceptional conformation outstanding performance pedigree but has a nasty attitude bred to a mare that is a half sister same great conformation etc...but again not the best attitude while the chances are you will have one really nice horse conformation wise it may or may not be manageable because along with the desired traits it gets the not so desired traits x's 2 with each generation line bred it continues to duplicate over and over, The same goes with conformation any little flaw with each generation it becomes more & more pronounced.

Impressive was definitely line bred, to Three Bars, but I'm not sure if they've been able to prove that's how he ended up with the genetic mutation that causes HYPP or not. He was definitely the origin of the disease... He sired almost 30 world champion halter horses and to date has around 100,000 descendents...

In the beginning owners of his foals started noticing a wierd muscular twitching type of issue, they were usually mis-diagnosed as tying-up syndrome or colic, it took a pretty long time before they figured out that it was caused by hyperkalemic periodic paralysis.

At the AQHA 2004 convention a motion was passed to set January 1st 2007 as the date after which foals testing homozygous for HYPP would no longer be registerable, with mandatory testing for HYPP for the descendants of Impressive. The Appaloosa association set their date for 2008 I think. I'm thinking the Palomino association also has a rule.

It's kind of a shame that people remember him more for the disease then his show record but I geuss that's the way it is huh? I love Impressive horses by the way... I'm sorry that was off topic, and it didn't answer the questions which was... "did line breeding cause the genetic mutation..." It may very well have played a hand at it...

No, it is a shame that that is how he is remembered - It's like his name is a dirty word to some people. I jump at the chance to own an impressive descendant, as long as the individual is N/N!
I'm thinking that the line breeding had at least something to do with it, it's an odd thing to judt "happen". I know a person who has the people version of HYPP. It's actually the exact same thing.
