Twins are cool

Congratulations! Great pictures
For those who are asking, genetically identical reptiles often have strikingly different appearances, even if they're incubated under virtually identical conditions. I've hatched countless genetically identical reptiles, in some cases dozens of them, all clones of each other (mostly Clone Geckoes of course). The colour, pattern, scalation, even behaviour and physiology all vary, partly it is random (much like finger prints in identical twin humans), party it depends on egg quality, partly it depends on incubation conditions, temperature probably being most important.
I saw the same thing while cloning (parthenogenetic) insects in the laboratory. If you're enough of a nerd, there is a heap of material available in textbooks and science journals.
