Don't mean to give you a hard time, but: isn't it just as much speculation that there might be a homozygous spider as that spider might be homozygous lethal? No one seems to have any good proof of either so why would one opinion be more likely than the other.

Also, if homozygous spider is possible then the difference between seeing the first one and proving it through breeding should be a limited number of years. What I'm getting at is why should everyone have given up on ever seeing a visually different homozygous spider years and years ago yet still hold out so much hope for proving a non-visually different homozygous spider through breeding? I realize every spider doesn't get bred at two years, especially the females but when was spider declared dominant anyway?
