I was just assuming that people asking the question about super spiders know what super means so I didn't bother explaining it. My bad. XD

If the homozygous is lethal it is automatically not a dominant trait. Every homozygous lethal is technically a co-dominant/incomplete dominant due to the different phenotype. i.e. death. For example, munchkin cats have a homozygous lethal. Homozygous munchkin cats fail to even gestate so performing genetic testing on that is out of the question but it is known that it is a homozygous lethal.



In theory yes. Any of those outcomes would happen to be the case except the infertile egg part. What seems to usually happen is that the egg will be good but will die before hitting even the embryo stage. It's rare to get the white snake in general in that pairing.
The hobby using a term a certain way does not make it correct. My point was exactly that if it is lethal you can not prove which forms of dominant it is. There are still well known people working with the gene saying that it is not lethal, so I am not convinced it has been proven to be lethal.
