Science has seen that a lot of things which were
stamped earlier as
"social" components are much more heavily influenced
by genes... and vice

That would be jumping to conclusions. In some cases,
people may be more
aggresive, e.g. when the have a mutation in a
dopamine uptake gene.
However, such a simple model never explains ALL
forms of aggression.
In conclusion: we are influenced by our genes and by
our surroundings. Of
what a certain type of behaviour may be the result
will probably never be
explainable completely. Trying to answer this
question also carries risks:
people tend to overinterpret scientific results.
