Notes -
I like your theory for this much better than mine, but I do have my own:
"Momma's baby, daddy's maybe" is an eons-old problem, and combining the lower certainty of paternity with the (typically) higher violence of males suggests there's been a long history of some nasty evolutionary selection pressure for kids to resemble their dads more than their moms. Infanticide in non-human primates and many non-primate mammals isn't uncommon, even many human "civilizations" took our damn time before deciding to punish it, and before agriculture it may have been a common form of birth control in tough times.
I'd guess even a couple million years of this would mostly affect which genes control appearance (or mediate other genes controlling appearance? there's not that much Y chromosome...), though, not habits. My interracial marriage is N=1, but while my kids look much more (75/25?) like me than like my wife, their personalities are maybe 55/45 on average and no more than 40/60 in one case.
