Can someone please explain what this looks like? I hear that many het for Spider BPs, have a wobbly head. Does the head basically wobble while the snake is about to strike at its prey? Or is it a constant tremor?

There is no such thing as a "het spider". Co-dominance = no hets.

Actually most if not all spiders seen so far are het for the spider gene. Without knowing what a homozygous spider is like we can't say yet if it's co-dominant or completely dominant.

It's the spider itself that has the wobble head. It is very noticeable and does not look like a snake about to strike.

Spiders were inbred like you wouldn't belive to try and produce a super form and MANY of them now have wobble heads.

The sad part is a wobble head offspring can appear in a clutch from an animal that doesn't show the defect just as one with a wobble head can produce offspring that do not show it. You never really know.

If you see it, you'll recognize it.

IMO it is some type of neurological disorder although it hasn't been proven and a large producer of spiders who inbred the crap out of his will tell you that the wobble head is just cosmetic.

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.

with Randy. The problem doesnt seem to cause them problems it also tends to go away with size and age.
