There’s very convincing evidence that ability to use language is genetic, up to specific kinds of brain damage and specific kinds of genetic diseases that cause very particular types of language impairment. Language itself is memetically built on top of that.
I’ve never seen such evidence for any other kind of behaviour.
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?
