It depends, sometimes its difficult to say whether the trait has a biological cause which is what is passed on and we just see the surface expression we interpret as a personality trait. Its not impossible, I said it was rare. I haven't really studied the subject that much.

Sometimes artists come from family lines that have never had an artist of note. Its difficult to judge how talent comes about. If one believes in transmigrating souls, genetics may actually have very little to do with it. Certainly, talent associated with physical activity can have a genetic trace.
