Genetics can impact they way you adapt to a social group?

In a recent article, scientists have found a correlation between genes and how a person adapts to a social group. Scientists from the University of Edinburgh have studied over 1000 sets of twins and found a relation between their genes and how they adapt to social groups. The scientists studied identical twins and fraternal twins and found that the identical twins, who share all their genes, had very similar responses when asked about social groups and the ability to be flexible between other social groups that they do not belong to. On the other hand, the fraternal twins, who do not share as many genes as identical twins, gave different answers about social groups and ability to adapt to different social groups. Also, another interesting fact was that family ties had less influence on environmental factors, whereas ethnicity and religion seemed to have a greater affect on environmental factors that influenced what determined how successfully a person would operate in a group. I found this interesting because I always felt that the way you were raised from your family would affect how you would adapt to a group. I guess that your genes influence more than you would image.
