I think you misunderstand the nature of parenting pal.
I think it's likely you're applying an evolutionary explanation to your parenting behavior, but don't really care that much about your children's actual genes. You care about your children as persons, not their molecular machinery.
If you really, really cared you would have your genes cloned and be donating massively to sperm banks and what not.
I think mine is actually the simpler explanation, and yours is reaching a bit. We're surrounded by vicious competition for genetic reproduction, I don't know why humans would be the exception.
And I don't want a clone, I want to pick a partner with all kinds of good genes to bring to the mix and toss them together, which I did. A partner I'm attracted to in part because of a lot of cues she gives me indicating her genes.
I think when you've had the pride of a son or daughter who is the spitting image of you, or walks just like you, or is noticeably muscular in the places you are, it's hard to deny exactly where that is coming from..
Anyway, there was an interesting philosophy podcast that rejected reductionistic evolutionary explanations for human behavior. The reasoning goes that yes, evolution is responsible for creating our minds, but once we have the ability to be conscious, to reflect, ask all sorts of questions and form new ideas and what not, that this is a new level of explanation. Thus the need for psychology, sociology, etc.
Call it an emergent if you like. Evolution itself is emergent upon physics, chemistry, geology, climatology, etc.
