Eh, not exactly. I'm thinking of fertility as providing information to each partner on whether to cooperate or defect. There is much more uncertainty about the fertility of other potential partners, so each just goes by physical appearance.
the ESS concept only makes sense when the “strategy” in q (here: the individual’s pay-off function) is transmitted to the next generation via reproductive success

yes? i'm not sure that's contradictory to my original formulation. the question is what kinds of decision rules could be an ESS, and under what ecological circumstances. many skeptics of monogamy act as tho it could never be an ESS, which is false. That said, ecologies change.
