This is what really concerns me about the desert female issue. The few reports I've read of breeders posting their desert female failures involve the female becoming egg bound (not just slugging out). IMO there's a big difference between an animal that just can't reproduce, and one that is at risk of losing its life if it tries. (And yes, I know that every female animal is at risk of losing her life through breeding -- but if it's almost a given with desert girls, that makes me seriously question if I would want to work with the gene.)
If the girls are just sterile -- no death involved -- I would still love to pick up a desert male. I think it's a gorgeous morph with some knockout combos. I just would be worried about producing females if the females were doomed to dystocia and death from breeding.
