Wrong all around. No wobble genes are recessive, especially not spider. Also, due to rumors of double doses of many of these genes being fatal they tend to be the least inbred genes out there, so inbreeding has little or no effect on the wobble of future generations.

From all observations I have personally seen or heard of, the extent of the wobble in snakes with these genes are totally random and can change as the animal ages. If a normal, mojave, or any other snake without a "wobble" gene present appears to have the same neurological tick, you should consult a reptile vet about it.

Here's a good list of genes that have known issues and a detailed explanation of those issues
