@TomServo:

I got the impression that Mordin's loyalty mission allowed several times for Shepard to either encourage or discourage the salarians' use of the genophage. In my most recent playthrough, at least, Mordin seemed very upset about the fate of the krogan after the genophage (with Paragon options), and seemed to want to make amends. Specifically, when Shep asked him if a unified krogan society would be better in handling aggression (like the one Wrex is trying to create) he said it wouldn't lead to as many issues as having them divided.

Also, concerning the Admiralty Board: I hardly think Bioware would invest so much effort in allowing Shepard (numerous times) to either encourage or discourage the quarians' war/peace movements, just to take it out of players' hands and decide for us. I think it'll be handled by appointing Tali as the new admiral, with her preference for war or peace determined by Shepard (or maybe just influenced, based on the dialogue in ME2).

But who knows? Anything could happen in ME3...
