There's no practical point in separating genetics from life experience, as they go hand in hand together.

Someone who has the genetics to be physically attractive/beautiful will have a completely different set of experiences than someone who isn't. Same goes for intelligence.

Also, the source you linked only pertains to IQ (which itself is not a perfect measure of intelligence), and IQ is not personality (although I have met some folks who do treat their IQ as a substitute for such).
