I feel that it's difficult to measure intelligence, and a person's intellect shouldn't be measured purely based on their academic standing. I can use myself as a minor example - I'm as smart as anyone in my History group in University, but I don't get particularly high marks because it's not the way I'm comfortably learning.
A major example? Take a redneck who lives out in the wilds of the Deep South in the US. Dropped out of school at age 12. Probably knows far more about stomping around the woods and hunting crocodiles, and whatnot, than a University graduate.
In my opinion, there are many different kinds of intelligence. Many different types. If hereditary intelligence does exist, it is not for one type of intelligence, it applies to all, which is my personal opinion on the matter. However, our experiences in life also shape our own personal intelligence, regardless of what kind of intelligence that is.
