Passing on the wobble

I have always thought about this, would it be possible for an offspring of a spider to inherit the wobble without it being a spider itself?

My understanding of the mutation with the spider gene that creates the wobble is that it must be a visual spider or spider combination to have the wobble.

This is correct.

No.

And the fact that it doesn't happen is the biggest argument why the wobble can't be 'bred out' of spiders.

Hi,

There are indeed normals that show the same kind of wobble as spiders - now whether the cause is the same is unknown. In the two I can think of offhand only one had a known parentage that included spiders.

It does seem to be fairly rare though.

Good point del. I'll chime in with the little I've read up on snakes and motor control issues.

I've seen a few individuals of various species of snakes reported to have motor control issues, including ball pythons that weren't spiders. The BP I can recall seeing a vid of was not the offspring of a spider.

The other snake species were not offspring of BP spiders.. obviously. Some were "normals". Some were morphs. In particular, the "jaguar" carpet python morph has "neuro" issues associated with it.

Much like there are many issues that might cause motor control issues in humans (parkinsons, huntingtons, MS, Tourettes, MND, and I'm sure there are more), I'm sure that there certainly are a variety of causes of motor control issues in snakes.

I hatched a male super pastel (not a killerbee, no spider in him) out of a bumblebee male that had a head tilt and stress-induced spin just like his dad.

... The clutch got stressed during incubation and had some issues, though, so that might've been why. Still, though -- the super had the exact same neurologic signs as his bumblebee sire.

I think it's remotely possible that the spider gene and the "neuro" gene are on separate loci, just very, VERY tightly linked. That said, even if that's the case, it's almost a moot point since they clearly get inherited together some 90-something odd percent of the time.*
