Isn't this wrong?

Honestly this is what had been bugging me about morph breeding [especially "Super" types] for a long time; I still don't think I'd be comfortable purposely inbreeding/linebreeding if I had my own

Sounds like you're looking at the situation from the perspective of inbreeding in mammals, which is not the same as inbreeding in cold blooded reptiles.

Keep in mind that there are small pond environments all over the world where the local frogs and turtles have been inbreeding since the dawn of time.

As others have said, the difference between mammal inbreeding and snake inbreeding is pretty big. I had a hard time wrapping my head around it when I first started researching ball python breeding, but four years later I've gotten pretty used to the idea (and it plays a big role in a recessive project I want to do). New blood is always good, but there's no need to go to great lengths for absolute unrelated pairs throught your whole breeding plans. Though if that's the route you want to go, you can do it by all means! I'd imagine it'd get expensive fast though.

In reality, it depends on the genetics of the animals. Like someone mentioned, it can bring out desirable and undesirable traits but that depends on what the animal carries. It just depends on the line. Even mammals are line bred on a regular basis if you look at the lineage of purebred dogs, cats, and horses. It enhances certain traits and in some cases, makes you realize that there was an undesirable recessive trait there when you get offspring who express it. Also, remember that siblings are not 100% genetically similar so one may carry an undesirable gene while the other might not thus producing offspring who may carry it but won't show it.

Here's an example. Let's say you're trying to get albinos and we'll pretend ultramelanistic is an undesirable trait.

As you can see, these two could be siblings who were bred but because one didn't carry the negative gene, none of the offspring were affected. In this case, you wouldn't know that any negative gene was carried since you got all healthy offspring

In this example, both parents carry the undesirable trait and so you see it in the offspring telling you that the genetics are there. In this case, I wouldn't do the pairing again because you know that both parents are carriers. By bringing in outside blood in this case, you'd lower the risk.

That makes sense, thanks for that.

I had added the little story in my former post as I wasn't sure if the deformities of the snakes [missing eyes] were a result of line/inbreeding or something else? [and if it's something else, what could it be? o.O]

It's just that there are probably some out there who go for the minimal investment for the most profit, with all of them relating back to the first pair that was obtained, or possibly further back if the pair were related too.
So, ideally, if there are no bad effects from inbreeding what's stopping people from doing things like this? Would having a 6th generation line/inbred super-something really be possible with no issues as long as said "super-something" was a genetic morph or trait that was desirable? o.O I'm just a little sceptical that it can't be *that* easy, but if it can, well... ok *shrug* I'm wrong :B

I have no doubts there are quite a few multi generation inbred animals out there. Unfortunately there is no real way to know unless you produce everything yourself. Even then do you know with certainty where your original snakes came from. The point is to not perpetuate the scenario and try and put new blood in your lines. I would even do something like trade straight across for the same animal just to get new blood (ie, Mojave female for Mojave female).
