Well it's not one, but more than one, but it's a valid point to say that a few desert females laying viable clutches do not a viable breeding morph population make.
It will take more than that to prove that desert females can breed successfully.
And I understand that ONE doesn't really affect the price on the females(pet quality), but my comment was specifically if it's been figured out how to breed desert females, or if it's proven that they are viable(not just this one), then I'd be happy despite the prices going up(IF they were now potential breeders rather than just a couple flukes). Otherwise I may still be getting myself a non-breeding desert female for a pet(it would go nicely with my non-breeding spider female, so to speak). I have a couple pets, and pretty snakes are pretty snakes.
And I generally don't compare humans with animals. Obviously human women have a lot more resources to deal with having a baby if they have complications. You can't really compare a hatchling snake with a human baby in terms of worth and risk assessment, at least in my opinion.
