That would be take on it Randy. There is a super form, it is just lethal.
And we call the Woma a co-dom so by the same token we ought to call the Spider a co-dom.Which also touches on another small point, would woma be considered homozygous lethal even though the homozygous animals live for a while?
I think the big wrinkle is that the Pearl is the result of Kevin breeding his Type I Woma (aka Hidden Gene Woma) together... And it has just been assumed that the Type II (typical Woma) also produce a lethal super, which may or may not be the case...
