Question Statement :

Behavioral geneticists have found that the effects of being brought up in a given family are sometimes detectable in childhood, but that they tend to peter out by the time the child has grown up. That is, the reach of the genes appears to get stronger as we age, not weaker. Perhaps our genes affect our environments, which in turn affect ourselves. Young children are at the mercy of parents and have to adapt to a world that is not of their choosing. As they get older, however, they can gravitate to the micro-environments that best suit their natures. Whatever genetic quirks incline a youth toward one niche or another will be magnified over time as they develop the parts of themselves that allow them to flourish in their chosen worlds. _____________________________

Although it is true that fraternal twins raised apart have remarkable similarities in most respects, still the intervention of the environment has caused several differences in the way they behave.
However, it is still not known whether the more abstract attributes like personality, intelligence and likes and dislikes are gene-coded in our DNA, too.
The environment, then, is not a stamping machine that pounds us into a shape but a cafeteria of options from which our genes and our histories incline us to choose.
But even knowing the totality of genetic predictors, there will be many things about ourselves that no genome scan - and for that matter, no demographic checklist - will ever reveal.
