It's similar with most views and values. Your children will mostly share all of them with you once they reach a certain age. It's something I can even feel happening with my own parents as I age, rather to my distaste. hahah. Anyhow, yeah - there's about a zillion studies on this topic and you can find that parents values are most predictive of those of their children.
And of course with values and other characteristics, even if parental views/values are highly predictive, there's going to be some variance. But you still end up with the fact that if a bunch of people remove themselves from the gene pool, any definingly common characteristics of those individuals are also going to be disproportionately removed from society as well.
In looking up some literature on it, it turns out that some studies have even studied and found what I alluded to of people trending ever more towards their parents values as they age. [1] They call it 'delayed activation'. But anyhow, yeah they found the exact same thing where our values become even more alike as we age. Pretty interesting stuff! And I think it makes the age aspect quite critical. I assumed I was one of those exceptions referenced above, yet reality had other plans in mind, in spite of my protestations.

No, they don't. If that was true, we'd have prehistoric values. (It would mean you could turn matters of culture into genetic arguments, which is fun, I see the temptation, but it's just not true.)
