The spider is considered to be dominant since it does not have a known super form, but it does not always give spiders so therefore when you do a square it should be written as Ss and not SS, right. If so, breeding two spiders together should give you 25% normals 50% spiders and 25% super form, but since there is no super form, what does this become? Another spider? Does breeding two spiders give you a 75% spider and 25% normal. What happens to this fourth of the square? I have heard the idea that the super form of the spider is lethal and that 25% that would be the super simply die before they can form (infertile eggs, eggs that go bad during incubation) What are your thoughts?
