For a good take on Genesis I suggest you read the Genesis Wave trilogy by John Vornholt.
Book one: Excellent
Book two: Good
Book three: Passable.
Normally I can't stand John Vornholt novels (how would the Voyager EMH put it? Rather lowbrow). But this story isn't too bad.
Overall the story does have a good take on what happened to Genesis (it was covered up after the Genesis Incident) by order of the Federation Council.
The story is a little contradictory after this point as apparantly the Romulans, Cardassians, Klingons, Tholians, Breen and Gorn all signed the Genesis Non-Proliferation Treaty preventing them from developing a Genesis Weapon (although the Klingons were believed to have been in breach of the treaty as the explosion of Praxis was primarily thought to have been the result of a problem at the Genesis labs there). But by signing this treaty all the other races in the Quadrant know what Genesis is so why would Federation then bury it's research.
Anyway. Genesis information was kept by Starfleet Intelligence (but of course) and it was review from time to time but the possibility of the Genesis technology falling into the hands of the Borg or the Dominion was too high meant that nothing was ever done with it. Dr Carol Marcus was kept in protective custody on Pacifica ever since the incident (and was still there as of mid-2375). The Genesis Cave in the Regula 1 asteroid is still thriving as of 2375 as well.
Anyway the books are worth a look and the Genesis Re-evaluation Report in Chapter 12 is fantastic (and not written by the author either).
We have all your working biros and we're not afraid to use them.
Leave a box of used postit notes and a box of paperclips inside the filling cabinet and things won't get nasty.
