Now does the double spider gene combined together at meeting cause the egg to die or become infertile, could be. There are just WAY to many things going on with genetics that could cause people to never know a homo spider exist. It could be that there is more going on with the spider gene than it being just "dominant". Who really knows. But that is really moving out of the world of snake genetics and getting into the real genetics of animal species.
