Today Keltham is going to try conveying some of the absolute basics about population genetics, which was on his mind during lunch today for reasons which need not be explained. (Keltham actually says this part out loud.) These basics are not all of the knowledge Keltham has out of dath ilan, there are advanced tricks he's deliberately not going to cover until they're bought from him, but he's wondering if even the basics will be self-evidently useful enough that it gets him enough credit with the Chelish government to cover things like Detect Magic goggles.
Also, after his experience with how Chelish education is set up, and having been told what the average Intelligence on this planet is like, he feels some degree of concern, and a need to check that current heritage-optimization programs are not being run, like... backwards.
Before he launches into his own lecture, what're Cheliax's current knowledge or hypotheses about genetics, and how have they set up whatever current heritage-optimization programs they're running for crops, domesticated animals, and people?
