The Adventures of Auck

I'm thinking about running an experiment into a genetic basis for the inheritance of cultural traits:

Hypothesis:
Cultural traits (fashion sense, taste in music etc.) are genetically determined, so that people with similar genes will tend to learn behaviours in the same way.

Method:
Get two identical twins.
Separate them until they both decide to get a hair-cut.
Record their haircut choice.

Prediction:
If one subject shaves off all his hair, the other will too.

I'm thinking about calling it the bald-twin effect.
