How Many Morphs Are Created Through Inbreeding?

[aalomon]

I've started to notice a somewhat not very talked about topic. The more i have looked into BP's, the more i notice very serious genetic problems with the more complex morphs. The Spider wobble didn't seem that much of a problem at first, that is until i started noticing some morphs inheriting "Duck bill" deformed mouths. I've even seen some morphs having blind eyes or even no eyes at all! Seems that the same thing which happened to dogs during the 1900's in Britain is now happening to BP's. Now i would greatly assume that the majority of you guys probably don't breed brother to sister or brother to mom, etc. but it does seem that has happened numerous times with other people and will continue happening. Is this some thing which is looked down upon?

Dogs are very different from ball pythons. When breeding dogs youre trying to concentrate many polygenetic traits into a single animal. Your odds of this happening greatly increases when you line breed for generations and end up with a very limited gene pool. Inbreeding its self does not cause issues, but limiting the gene pool so severely magnifies any unwanted traits as well as any desired ones.

On the other hand with snakes the genetics we breed for are much more straightforward so outcrossing doesnt dilute the desired outcome.

Example: If there was 1 german shepherd in the world and you bred it to a lab, it would take a long time and a lot of inbreeding to get back to a "pure" shepherd. On the other hand if you take a pastel and breed it to a normal you get pastels in the first generation.

What about when it's a brand new morph? For example the new scaleless BP's will they breed them together to increase the amount they have?

Somewhat, but remember people also want to make combos with a new gene so new morphs have a lot of outcrossing done as well.

So the actual gene itself contains the wobble? Why do some Spider's of the same morph have varying degrees of the wobble in them?

Similar to why pieds can have varying amount of white, all spiders have wobble but the degree varies between individuals (the original spider wobbled). Actually spiders were one of the first popular ball pythons morphs so people bred them with everything they had, inbreeding had nothing to do with the wobble.

Ill also add this isnt a taboo topic at all. This exact conversation pops up on every forum a few times a year
