I am not sure what you mean—or how it is relevant. Plenty of behaviour has a genetic basis. Eating behaviour and sexual behaviour, for instance. If you look at all the reflexes and instincts out there, you will see that many types of behaviour have a genetic basis.
Even if everything was learned (the “blank slate” hypothesis) - so what? How would that be relevant to the idea of cultural inheritance being significant?
