Hmm, I thought I said that. Sorry if I mixed something up.

From my understanding, (and I could be wrong), Spider has not yet been proved Dominant. They're a co-dom morph with no known Super form yet. Spider to normal still only gives half spiders.... Dominant genes when bred with normals give 100% co-doms. (ie Super Pastels to Normals give 100% Pastels)

New England Reptiles has it listed as a dominant gene....

If you breed a morph animal to a normal and you get some morphs, it's dominant. Period.

If it is a dominant trait (not co-dom) you have no way to tell which animals are 'supers' or homozygous. So.. a heterozygous spider (which looks like a spider) will only throw 50% spiders in a clutch with a normal. A homozygous spider would throw 100% spiders in a clutch with a normal, but all of those spiders would be heterozygous spiders (carry one copy of the spider gene)

Super pastels (homozygous pastel) give 100% pastels when bred to normal.. yes. However PASTELS (heterozygous pastel) give only 50% pastel when bred to a normal.

The difference between dominant and co-dom is that dominant morph animals look the same as heterozygous and as homozygous.. and co-doms look different (like pastel/super pastel)
