These look like ghosts to me. I don't really see much Upper Keys influence in them, but then, my eyes aren't what they used to be and the images are fairly small. Photos of the parents would help (all 3 please) as well as the normal siblings for comparison. Belly photos would be really nice as well. If you want, for comparison, my caramel Upper Keys clutch is hatching right now. I have photos of the first 2 hatchlings out, with ventral shots. I also have some normal Upper Keys het anery caramel and hypo Upper Keys het anery caramel hatchlings. Yes, these are outcrossed to get the genes, but Rich (breeder of my parent stock) has done a great job at selecting the ones that still have the main characteristics of the "pure" Upper Keys (light color and minimal checkered belly) as all of the hatchlings I have produced show them as well. I may even have an amber Upper Keys, but need to wait until it emeges from the egg to verify it.
