Does human behaviour that is caused by inheritance depend on the environment and lifestyle in general?
I feel that 99% of the time that someone asks "are human unique concerning ?", the answer is nope. There's nothing exceptional about humans in this respect.

Rephrasing your question

Your question can be rephrased


  Is heritability sometimes different from 0 or 1 for humans too?


If you do not understand well why this is a good rephrasing of your question, then you should definitely have a look at this post.

Is heritability sometimes different from 0 or 1 for humans too?

Yes, humans are not exceptional in this regard. In humans, other animals, plants, fungi, bacteria, archeabacteria and for any other living things, any behaviour (and any phenotypic trait in fact) can have a heritability that differs from both 0 and 1, or in other words, there can be for any trait both genetic and environmental variance underlying phenotypic variance in the population.

In fact, very few traits that have a non-zero genetic variance has no environmental variance. Have a look at the post List of heritability estimates in humans? for a list of traits on which we measured heritability.

ADHD

The difficulty with a trait like ADHD is that the methodology to measure it vary a lot from one country to another or even from one practitioner to another. But yes, for ADHD too, there is both genetic and environmental variance underlying the observe phenotypic variance (Thapar et al., 2000).
