It is impossible to have a het. Spider, because when a morph is referred to as a het., it usually is referring to the animal being recessive heterozygous, which contains the gene for the morph, but it does not show because it needs to be recessive homozygous to be apparent.

I think it IS possible, and that all spiders ARE heterozygous. One piece of the allelle pair is spider, one piece is normal. Hetero means different, unlike, not the same. So they are heterozygous. Just because something isn't recessive doesn't mean it can't be het. People don't refer to doms and codoms as hets, but they still are, genetically speaking. A pastel is het, a super pastel is homo. A mojave is het, a blue-eyed leucistic is homo. I've heard of yellowbellies being called het ivory. You could call a pastel "het super pastel" and I don't see how it would be incorrect. Sure, no one calls them that, but it isn't wrong.
