The latter example is an example of culturally inherited altruism. But you're right, it's not genetic.
And yes, care of offspring (and related family in general) is very much genetic. Natural selection would tend to favor genes (and thus hosts) who care for their young, which would ensure that the gene gets passed into future generations. So you're right on both counts.
It actually also helps explain why male infidelity is higher than female. A woman can be 100% sure a child is hers. A man, less so. With the advent of DNA testing, this has changed somewhat, but not for nearly long enough for evolution to change our natural tendencies. In many species, a man is sometimes better served having multiple partners to ensure reproductive success than caring for one child, where there is a slight chance that he is caring for another man's child. Thus, natural selection tended to favor (mostly) doting mothers and fathers who are slightly more prone to cheating. Their genes tended to fare slightly better.
Part of marital fidelity is culturally inherited as well, so it's not entirely genetic. But both play a factor.
