HuDaFuK, okay! Shure, you're right about Clemens, I forgot about that moment, my Humanhumanalien theory is a little diferent, but the main idea is the same as yours. I understand that Queen was a mutant. Okay. BUT! How the hell alien DNA got in Ripley blood?! Alien Embryo can consume host's resourses and DNA, it adaptates to be biologicaly invisible to host's organism until chestburst (when it becomes just too big to hide). Human embryo never changes mother, any embryo never changes host. If no, than Ripley, Cane and all facehugged become mutants already? What a bullshit? If you have one blood type it's no guaranty your mom has the same type. The law of reason and consequense.
