I mean yeah, genetic memory would kinda suck for the purpose they have in those books, you would just see a million years of childhoods and youths. Alia would probably organised the craziest parties in empire though.
that couldn’t be explained from the new offspring’s perspective?
Not really, they mentioned memories of death, so assuming most people do not get concieved after the death of their parents (specifically mothers in case of BG) means those aren’t really genetic memories but just magic.
