But this story line of the "geni" genetics seems to have a touch of a flaw to it for me. It would seem that for Honor to be a "geni" her mother would also have to be one. Yet I specifically remember the plot line were Honor and her mother are talking about teaching the treecats to communicate via sign language and Honor offered her mother a cookie, which she refused, to keep her weight down. So Honor's mother is not a "geni". I suppose recessive traits can surface, but that would seem improbable. Or did Honor get her "geni" traits through he father??? Honor gets her height from him but I don't remember anything about him being a "geni" too.
Honor got her genetic modifications from her father. Yes, he is a genie, too. It goes all the way back to Honor's great, great, great, great-something family, the first Harringtons who emigrated to Sphinx from Meyerdahl. Meyerdahl was an even higher-grav planet than Sphinx, and genetic modification was almost a necessity to survive there. The genetic modifications were done in such a way that they would permanently dominate (apparently using some technique unknown to 20th century genetics). So the Harringtons of Sphinx have always been genies. In fact, somewhere in the text is the statement that a very large percentage of the population of Sphinx has heavy-grav genetic modifications.
They'd be in poor shape to live there otherwise - they'd be looking at health problems or spending most of their time in housing with grav plates working in the floors. (Put that down as another thing Alison Harrington accepted for the sake of Alfred.) And certainly Sphinx is a good place to move to if you are a heavy worlder and want a new home - it's wide open, the SEM is and has been a great place for personal opportunity and civil rights, and the RMN has liberated more than its share of genetic slaves, some of whom will be suited to high gravity living.
The heavy world modifications like the Meyerdahl mods were designed to get in and edit the genes contributed by the other parent to guarantee being carried on to the offspring. By early 21st century standards, that's way out-there genetic engineering - in effect, getting the sperm or ovum to do a simple genetic engineering job
themselves on the DNA contributed by the other parent - but without it, you'd have either heavy worlders growing isolated from the rest of humanity or interbreeding with them only at the risk of offspring who cannot thrive on their birth world. (And yes, RFC's confirmed that it DOES mean that their use of 'dominant' in reference to genes has changed over the course of 2000 years from ours.)
It's an instance where the Beowulf Code permits something that may raise eyebrows here, but remains consistent with their stance that genetic engineering is there to fix problems (such as those you may come by living on Sphinx or San Martin), and not to "fix" people relative to some standard humans assign arbitrarily, for sheer racial "improvement".
