While, you're not totally incorrect, you're not completely right either.
Bp morphs to Purebred dogs is apples to oranges. People are purposely selecting FOR those bad deleterious traits in dogs. It's not occurring randomly. (And for your information, you cannot breed son to mother in dog breeding. It is father to daughter. My boyfriend's mother breeds AKC champs. This is apparently part of "dog breeding ethics" because in the wild, many daughters would not leave the parent group or territory and breed with a father, compared to the son who does leave the group. )
But anyway.
Some morphs that have heritable issues, such as the spider wobble, don't get selected against and the reason why they're still here. (Same as those disastrous dog breeds)
However, breeders will always cull a deformed/kinked/fail to thrive snake. Many dog breeders do not cull their bad stock, which is why there are so many trainwreck dogs out there (ghetto backyard bred American bullys anyone?).
And BP inbreeding occurs often in the wild. Do you think snakes migrate to other locations to breed? No. They are a non-migratory species. Most reptiles are, which is why they are "so resilient to inbreeding". They're in the same general territory their entire lives and breeding with whatever snake around, aka most likely a close relative. The only differences is that the unfit are selected and taken out of the population. I'm not saying inbreeding is good or bad, it just makes the population have a higher homozygosity. Also why there are locale specific phenotypes. Sure, it can increase negative recessive genes. But it can also increase the positive. It just depends on the individual.
Think geographically and reproductively isolated species or island population dynamics.
Sometimes it negatively impacts populations (cheetahs), while sometimes it has no effect and even sometimes is positive (elephant seals or Humans in Iceland).
By being more homozygous, you are enhancing a population to be more fixated and having the same alleles. Bad or good.
I'm all in favor for outbreeding, don't get me wrong.
But to just say 'inbreeding *is* bad and health and wellness *always* go down' bla bla bla is a poor statement... There can be positive homozygousity in a species.
Inbreeding in any animal species is NOT good. Reptiles are just as prone to the issues as are everything else. Nature does have ways to help curb inbreeding. Ball Pythons do move, they are not isolated to small local areas. Most hatchlings do not survive from any one clutch. They are caught for sale, die from starvation, die from defects or are eaten by other predators.
A pretty decent read on the issue is:
