You could of course argue that environment in the womb is largely genetic (and has a 50% correlation with the kid's genes, which is damn influential).
But once we open that door we're going down an extended phenotype rabbithole where you can start to talk about social interactions amongst non-immigrants being partially genetic because of correlations within regions, etc, and hilarity (with a healthy dash of idiocy) ensues.
The greater point being that saying something is either genetic or due to environment is always a pointless exercise because there is no separation, there are merely genes that spread without ever deciding how to allocate blame or credit for their successes and failures.
