There are species who are resilient to inbreeding such as the naked mole rat. This has not been demonstrated for ball pythons. There has however, been many examples of inbreeding depression in both reptiles and amphibians. If you have have a good source that suggests otherwise, I would be very interested.
Completely true. These are incredibly common, but I didnt think it was relevant to the explaination.
Not
true. A genetic mutation comes in three different forms, positive,
negative and NEUTRAL. Neutral mutations are slight differences in a
gene sequence that have absolutely no effect on the organism. These
happen more often than you might think.
