“Yes, Your Grace,” she said positively. “For one thing, it explains the two things about your population which have most puzzled the Star Kingdom’s geneticists from the beginning of the Alliance.” Sullivan raised an eyebrow, and she shrugged. “I’ve already mentioned the incredible rapidity with which your ancestors evolved a ‘natural’ defense against heavy metals. That was number one. But a disparity in male-female birth rates on the scale of Grayson’s, while not all that unusual under distressed conditions, seldom lasts as long as yours has.”

“I see.” He gazed at her meditatively, then drank more tea. “And is there anything which can be done about this, My Lady?”

“It’s really too early for me to say yes or no to that one, at least with any degree of confidence. I’ve isolated two or three possible approaches, but the site of the problem may well make things difficult, because the mutated gene on the X is near the zinc-finger X protein gene. That’s a key gene in sex determination, and it’s at the Xp22.2—” She paused as his expression began to indicate that he was lost once more.

“It’s at a locus where changes can involve literally dozens of disease states, Your Grace,” she simplified. “Many of those diseases are lethal, and others can cause disorders of sex determination. We know a lot more about sex differentiation than whoever whipped up your survival modification did, but we still dislike meddling with it, and particularly in this area. There’s a lot of room for small errors to have large consequences, and even if we avoid the more dangerous disease states, the Beowulf Code specifically prohibits genetic manipulation in order to predetermine the sex of a child.” She grimaced. “There were some very unpleasant—and shameful—episodes relating to that in the first and second centuries Ante Diaspora, and I’m afraid they’ve been repeated from time to time on some of the more backward colony worlds since. Nonetheless, I think I could probably at least ameliorate the situation. But whatever I do, it will take time to perfect the methodology… and probably result in at least some decreased fertility among your planet’s male population.”

“I see,” he said again, and switched his eyes to the holo image above the coffee table once more. “Have you spoken to the Sword’s health authorities about this yet, My Lady?” he asked.

“Not yet,” Allison admitted. “I wanted to be certain of my data before I did, and then your visit to Harrington gave me the opportunity to speak to you first. Given the role your Church plays in the day-to-day life of Grayson, I thought it might be wiser to speak to you first.”

“Obviously Father Church will have to address the issue,” Sullivan agreed, “but we who serve him have learned bitter lessons about meddling in secular affairs. I believe you should draw this to the Sword’s attention as soon as convenient, My Lady. If my offices can be of assistance to you in this, please tell me.”
