I have blue eyes, as does my mother and my two children. Do you think it is due to our similar upbringing and socioeconomic status?
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.
Almost all flamingos are pink. Do you think this is "genetic" the same way human eye colors are "genetic"?
(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.
