Question on line breeding.

[angllady2]

So, i've done a lot of reading here on the subject of inbreeding and linebreeding, and while I think I have a pretty good grasp of things I would like a few expert opinions on my plans.

I have 4 BP. Three 100% het pieds and a YB. I bought them all from well known, respectable breeders so I'm confident they are what they say and are all completely unrelated. My intentions are to breed my het male to both females.

If I am fortunate enough that each female produces one visual pied baby, and even more fortunate that one is a male and one a female, am I correct in my thinking that I can make a pair from them?

I believe that while they share the same father, the fact that they have different mothers would mean the chances of defects from breeding them would be very slim.

It is also my eventual hope to produce a YB het pied and breed it back to produce YB pieds.

Please let me know if my estimates are correct, or if I'm way off base.

All the BP morphs are inbred to some degree. Some morphs more than others. For example, I believe all spiders and spider crosses descend from one wild-caught male. Breeding one male to many different females doesn't make for a very diverse gene pool -- you still have half the genes coming from one snake. There's no guarantee bad things will happen with inbreeding, you're just way more likely to have two "bad genes" come together with inbreeding -- just like you're more likely to have recessive genes for cool morphs come together in the same snake.

Just like in dog breeding, ball pythons have two genetic strikes against them: "popular sires" and "insufficient founders."

Inbreeding has shown little aliment effects on ball pythons thus far. Many people breed a mothers offspring back to the mother with no real issues. It takes many many generations to see if the issues will form but none have come out as of yet.

Things like wobbling of spiders and kinks of caramels are genetic trait deformities that are attached to the specific alleles. As far as I know, those don't have anything to do with inbreeding (the first spider we found had wobble).
