Gene connection

Banging head against a wall
Eating so much that you have to puke
ROFL - literally
Morning person, early to bed
Dancing with funny moves but still need to dance
Killing ants almost as a habit
love for animals
love for water

Does any of the above passes as a hereditary trait? Maybe the last two points can be generalized for most kids. But what about the rest of the list?

I am sure my son has never observed me doing any of the above. As a child I used to have all of the above habits. And my son also has those. I am unable to see the connection. How does he know?
