Human twin studies suggest that aggressiveness is heritable, and impulsive aggression is particularly so. Studies have shown that identical twins, who share 100% of their genetic material, are more similar in their level of aggression than fraternal twins, who share only 50% of their genetic material. This indicates a genetic component to aggression, and studies have also shown that impulsive aggression, which is characterized by sudden and uncontrolled outbursts, is more strongly influenced by genetics than premeditated aggression.
