I'm just tossing ideas out here, I have no proof; just my own opinions.

If spiders "wobble", wouldn't the spiderxspider pairing increase the amount of "wobble" in the offspring, and by inbreeding a son/mother spider combo make it even worse? I've seen a lot of people here against inbreeding (as I am), and some who do it with no thought whatsoever (usually driven by the desire to make expen$ive offspring).

I have a pair of breeding spiders, but I'll never put them together...
