"That’s a fine example," Moira returned. "As it happens, Old Earth compiled vast databases on such things before its destruction. All of which are in there now." She gestured in the direction of her lab. "We have a very good idea which defects, on which chromosomes, are responsible for alpha-thalassemia. If you supply me with an ovum, I can find those defects and I can fix them before we begin parthenogenesis. Your offspring will be free of that defect. Barring some random future mutation, it’ll never return."
