Discuss genetic explanations for aggression. Early research concentrated on chromosomal abnormalities but no specific genotype has been associated with aggression. Genes determine how much testosterone a person’s body produces and how quickly it circulates around their body. Genes also determine the synthesis of testosterone receptors‚ and how many and how sensitive such receptors are. The gene called monoamine oxidase A (MAOA) produces an enzyme which regulates the metabolism of serotonin in

Genetic influences on aggression Genes do not directly cause aggression but influence elements of our biology that contribute to it. This can be demonstrated through the following methods; 1.Animal Breeding Studies In animal breeding studies‚ animals are selectively bred for certain traits. If it is possible to breed for aggression‚ this would suggest that genes contribute to aggressiveness. Lagerspetz (1979) bred 25 generations of mice.

This shows the nature of the inmates as well as how they were brought up and accept other values. This is also supported by Blomberg & Lucken (2000) study on inmates. However you could counter this point by saying its reductionist because it reduces down behaviour to measurable units. Weaknesses

The hormone testosterone is most often discussed in the effects it has on aggression‚ but it also plays a part in other roles of behavior. “During human puberty‚ there is a 20 - to 30 - fold increase in endogenous testosterone production in males. This increase in testosterone affects changes in aggression and causes an increase in risk taking” (Duke‚ Balzer‚ & Steinbeck‚ 2014). The amount of testosterone one has in their body has shown to play a role in their behavioral tendencies. Studies show

Evolutionary explanations of aggression Evolutionary psychologists argue that reproductive challenges faced by our ancestors can explain the aggressive behaviour seen in people today. A man can never be certain that he is the father of his wife’s children unless he prevents her having relationships with other men. This can explain why male jealousy is often cited as a cause of domestic violence. In many countries it is seen as acceptable to murder an adulterous wife or her lover e.g. among the Nuer
