If you put half immortal/half mortal (Demigod) with another half immortal/half mortal than technically the equation would still be half immortal/half mortal. i.e. if Percy and Annabeth had a child, the kid would be half immortal (quarter Poseidon, quarter Athena) and half mortal. a quarter blood would be a half immortal/half mortal with a full mortal as a quarter of them would be immortal and the other three quarters would be mortal. And coming up from MattShadow's comment, Legacies would be a better, but not very accurate, term as it implies a decent from a single or several gods. Also coming from an unknown contributer, many Greeks actually did survive and still have decendants like Odysseus, Jason (the first one), and Orpheus.
