It doesn't seem likely to me that there has been much inbreeding in spiders. Very often I read of young spider males being bred to lots of normal females. Spider really isn’t that old of a mutation and with the much quicker maturity of males there should be way more breeding male spiders than females. Add to that the dominant factor where a morph male can be bred to many normal females and I would expect that the vast majority of spiders produced so far are from male spider X normal breedings. Sure there might have been some inbreeding trying for a super but now I’m seeing posts that people have given up. Even if every available adult female spider where still dedicated to inbreeding to attempt to produce a super spider their offspring would only be a small percentage compared to the offspring of all the breeding male spiders X normals. I don't think inbreeding is to blame. The reported pattern of inheritance suggests to me that the spinning is probably a side effect tendency of the spider mutation it’s self.
