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.
Actually modern genetics has shown that there is no such thing as a dominant gene. Rather there is a mechanism that HEAVILY weights genes available. Linean genetics as explained in High school and even most College texts books is out-of-date, and heavily leaning towards blatantly wrong. We are beginning to understand there are far fewer mutations than we have thought. So far the total amount of so called "junk DNA" keeps shrinking as our understanding of what/how that so called "junk DNA" works. We started with what? 25% "junk DNA". That dropped to 15% a few years ago and now that number is well under 5% and most in the human genome mapping project are positive it is 0% if not very close to 0% and we simply do not have a clue yet.
Beyond this my ability to decipher what is going on vanishes and to get this far I basically leaned on my sister to interpret what she has been sending my direction.
PS. I made it up-through microbiology in college(minor in Biology), but honestly my love was in mechanical engineering.
