I think Desert females should be safe so long as their owners don't try to breed them. They should probably be sold with a certificate to that effect, or something. (I am one of those who thinks their infertility is a done deal at this point, and no amount of skewing temperatures or whatever is going to fix it).

The reason i think people will be revisiting the desert ghost is because the two morphs have a lot of similarities in appearance, so they may make combos that likewise are similar in appearance. The type of gene involved is less relevant to that. (Actually, using a recessive gene keeps the value higher).
