A few weeks ago, I noticed a personality "quirk" in my 14 yr old daughter that had disappeared in my own teens. I've never told my wife, no one else has told her (not alot of my family left to tell it, they might not even have been aware). It's specific, non-subjective. It seems almost impossible that it should be genetic (but I have no other idea how it might heritably transmit). The idea that personality is heritable is, to me, not farfetched at all. My son is 11, I'll get to see if he does the same within a few years.
