Not morphs
While I am not a genetic specialist, I do know that leucism is an inherited chromatophore (pigment cells) defect. Simply put, the body surface, or the portion of the body surface which is leucistic, lacks the cells that produce pigmentation. Leucistic animals lack the 3 types of mature pigment cells...namely malanophores (they synthasize melanin, the black and brown pigment cells), xanthrophores (the chromatophores responsible for yellow, red and variations thereof), and iridophores (these cells reflect and refract colors)
Those chams are not "morphs" and yes, it IS an inherited defect. They are the product of mass interbreeding, so certainly the gene pool has to be weakened.
I think Tyler said it best, "They're fragile enough when they're not retarted." LMAO Tyler, very good! Nope, not much market for a retarded cham.
