Two things have been universally true the more we learn about the human genome: 1.) It's startling just how much is determined by genetics 2.) It's startling just how little is determined by genetics How is it that both are true? We are constantly learning that genetics is a strong determining factor in a number of seemingly complex traits, everything from the way you comb your hair to your food preferences and more. A recent study found a single genetic locus in mice can entirely alter the manner in which they build tunnels! But these are all seemingly complex behaviors. We are often surprised by the genetic control over such things because we can analyze these behaviors and break them down into discrete steps. To think that all of these steps, in combination, are controlled by DNA is frankly quite disturbing. It makes you wonder just how much can be determined by genetics. It might even make you question who you give access to your, or your offspring's, genetic information. You know what is an even stronger determining factor of overall life quality, though? The Marshmallow Test (http://en.wikipedia.org/wiki/Stanford_marshmallow_experiment http://en.wikipedia.org/wiki/Stanford_marshmallow_experiment). As humans, our key defining characteristic is our ability for higher cognition. While it is true that genetics provides the pallet from which your brain paints its cognitive abilities, the reality is that your children's brains will continue growing, developing, and changing for years to come. As the parent of identical twins, I expect you will get the chance to experience first hand just how much environmental factors can cause cognitive development to diverge, given the same starting genetic material. So, yes, if the NSA got a hold of your genetic information, they might be able to determine that they should serve you steak, and not a salad, at dinner when they are attempting to recruit you to become a double agent, but they certainly won't be able to predict how loyal, hard working, diligent, or resourceful you would be in the position.
