There is no proof at all that the "wobble" is inherited/genetic. Spiders with the "wobble" can and do produce spiders that are 100% problem free. The problem could very well be developmental/environmental .... just like there is strong speculation that the amount of moisture in the incubation medium can have an effect on caramels kinking, a similar situation may be true for spiders.
But do you really believe that either the spider spin or the caramel kink isn't genetic? The sporadic nature with which both are seen could well indicate a developmental or environmental component but it sure sounds like both are way too common in their respective lines not to also have a genetic component. What percentage of non-caramels are kinked, maybe 1%? If 50% of the imported caramels have been kinked that comes as close to proving a genetic link as I think we are going to get. Same with the spiders. Even if the animals picked for display at Daytona where a representative sample and 3% of them spin that is way higher than spinning in non spiders (I think I've actually heard of one). Of course I think people avoided taking spinning spiders to Daytona like the plague and only a few of the most eye popping combos made it irresistible to leave them at home. So basically I'm calling BS on your post trying to give the impression that you really believe that either kinking in caramels or spinning in spiders might not be genetic.
