varied reproductive expectations which should be predictable by fairly early childhood.
What do you make of the claim that boys are good for marriages?
It fits if you assume that the low variance of the daughter’s fitness makes it less responsive to the father’s presence. If the son’s fitness is predictable early, this should be reflected in modern divorces, though I don’t see offhand how to test it.
