Are personalities heritable?

Do you think personalities and personal qualities are heritable, /sci/?

One thing I've always found pretty insane is that Steve Jobs' biological paternal grandfather was ALSO a self-made millionaire (well okay Jobs was a billionaire but by definition that also made him a millionaire). But Steve never knew this guy, because Steve was put up for adoption when he was born. He never knew anything about his biological family until he was an adult, and he certainly didn't know anything about his biological grandfather who I don't think ever left Syria (Steve's biological father was a Syrian who moved to the US as a student).

Steve's biological father also seemed to have a rebellious, self-sure streak, since he defied his father's wishes by going to university, and as a student got arrested for political demonstrations. And he later became a restauranteur, thus demonstrating the same entrepreneurialism of his father and son.

Pretty crazy that the grandson of a self-made millionaire also became a self-made (m/b)illionaire, despite that grandson having zero knowledge of biological family, right?
