So, when discussing the books, we can treat it as a known and reliable mechanism -- even if it ultimately turns out you can't actually make any real-world version for humans.
Creating a mutation that
will be passed upstream is totally different and a far cry from creating a mutation that won't be passed upstream. Which is what we are discussing.
Life finds a way to exist. Not desist.
By the same token Jonathan, the author is free to pen an exception at some point in the future. Otherwise I agree. I was simply labeling that pill as another large one, for me anyway, to swallow.
I didn't really dig into the books' descriptions of locked mods; but I don't recall any definitive statement that they'd prevent any mutation within the locked mod.
I thought I recalled the descriptions just being effectively:
a) The locked mod is dominant; so its genes
will get copied into the final genome.
b) The locked mod is an atomic copy; you're guaranteed to get all of the genes comprising to it.
So you shouldn't get mutations caused by copying errors (especially from feralization), but I don't recall anything about it being immune to one-off mutations from, say, gamma rays hitting the DNA of an egg or sperm (or hitting the DNA of a person who has the mod).
In fact such one-off mutations in locked mods
might be one of the things that geneticist like Honor's mom treat in their practices -- but that's just my speculation. On the other hand though I guess there's also room for RFC to say that whatever mechanism allows the "atomic' copying of the entire suite of genes that form the lock mod also includes some kind of more robust error detection mechanism and it'll simply abort copying if there is a mutation within the locked area. (though how that mechanism could itself be protected from one-off mutation is another question)
It's not something I recall the books getting deeply into; so I've no idea whether his tech bible has fleshed out all those details either.
