I also believe that the wobbles and kinking are just another tendency of the respective mutations just like the color and in the case of spider also pattern.
However, I have seen a posts by large breeders (at least one of whom I trust) of large number of caramels with no kinks and a smaller breeder with a good run of non kinked caramels started.
While I think the tendency to kink is part of the mutation I think there must be some environmental factor that is reducing the chances of the kinks actually showing up in these collections (I’ve not heard of their customers having any better than average luck with kinking). Not much of a sample size but both of those breeders I'm told feed rats that are fed Mazuri 6F. Perhaps the caramel mutation causes ball pythons to need or not tolerate a nutrient non caramel ball pythons don't need or can tolerate.
It would be interesting to know if the caramels in these no kinking collections are more normal colored at hatching as if the Mazuri compensates for the caramel defect that causes kinking then perhaps it also compensates for the caramel defect that causes the caramel color. Maybe you would want to feed your breeders one diet and then switch the for sale babies to another to maximize color after you are past the spinal development stage.
