Since the Desert Ghost obscures the yellow belly highlights on the dorsal ridge and the belly patterning/coloration is of little use in this situation--only the sides are useful (which is a common occurrence in combos).
The pixellation is obvious under magnification. Pixellation such as that found on the sides of a yellow belly can also be seen in snakes carrying certain recessive Het genes, but, if yellow belly is a likely option--Occam's Razor would indicate that this is the correct choice.![]()
