I drive a pickup truck. Like my dad, grandpa and uncles. Do you think there might be a genetic compent to my choice of vehicle? Its strongly suggested as such, according to you.
Maybe genetics plays a much larger role in intelligence than we currently think, it's just so complicated that (unlike eye color) we can't identify those genes yet.
(It isn't.)

People telling you "genetics causes x" are committing abuses of notation if they don't include the counterfactual i.e. they are lying to you.
Everything about you is 100% caused by genetics - because otherwise you'd be a gorilla.
Everything about you is also 100% caused by the environment - because if a rock fell on your head you wouldn't have any "intelligence" after that.

Obviously, there is also a strong environmental factor. But lacking either, will probably result in no pickup truck.
As for our kids though, both drive Caminos.
