Bearded dragon from this site has one. http://ball-pythons.net/forums/showt...t=86261&page=2
To make one you have to get lucky. So far, paradox' aren't predictably reproducable.
That's not 100% fact. TSK has hatched out three hypo mojave paradoxes. No one knows how they are made. It could be a freak occurance, but there might be some complicated genetics involved, at least for some of them. It definitely seems like certain morphs have a far greater chance of throwing a paradox than others, so there is a possability that there is some kind of inheritable genetics involved in some cases.
