Answer:
Gene-environment interactions.
Explanation:
In gene-environment interactions, the field of epigenetics looks beyond the genotype itself and studies how the same genotype can be expressed in different ways. Scientists studied how the same genotype can turn out to be very different phenotypes. Gene expression is most of the time influenced by the environment in ways that are not always obvious. As we see in this case, identical twins share the same genetic information, their genetic material is exactly the same, but even with identical genes, there can be an incredible amount of difference in how gene expression can turn out throughout each twin’s life, one with schizophrenia and one completely healthy mentally.

Psychopaths are more likely to gain power through dominance, bullying and intimidation, rather than respect.
Psychopaths are often considered to be charming, engaging and smooth, due to a lack of self-consciousness which frees them from the inhibitions and worries about saying the wrong thing that can cause others to be more socially awkward. 
Psychopaths have a tendency to engage in risky behaviour without thinking of the consequences. This impulsivity comes from a lack of fear, according to criminal psychologist David Lykke.
It is commonly thought that psychopaths don’t feel any guilt or remorse, but recent research shows they are capable of such negative emotions, but only when something impacts them directly. In other words, if they hurt someone else, they won’t be racked with guilt like someone else might, but if a situation leaves them worse off financially, for instance, they may feel regret. Psychopaths know intellectually what’s right and wrong, but they don’t feel it, as one expert puts it.
Another key characteristic of the psychopath is that they mostly form superficial, short-term relationships with others, before casually discarding them.
