FreeBookSummary.com. The biological approach to aggression includes the belief that genetic factors play a role in aggressive behaviour and lies within an individual’s genetic make-up. There is supporting evidence of a genetic component of aggression. Psychologists have looked at twin studies to try and find evidence for a genetic basis o compare the degree of similarity of aggression.
They focused on the the influence of a particular genetic factor, the monoamine oxidase (MAOA) gene, located on the X chromosome, that produces an enzyme that influences the production of serotonin, a neurotransmitter that influences mood, appetite, and sleep and that inhibits aggression.

Genetic factors in aggression, including the MAOA gene. The ethological explanation of aggression, including reference to innate releasing mechanisms and fixed action patterns. Evolutionary explanations of human aggression.
In spots, xenophobia is an evolutionary explanation of group displays of aggression because natural selection favours genes that make humans more altruistic towards members of their own group, yet intolerant towards outsiders.
A thorough understanding of factors that influence aggression in children cannot be achieved without including behavior genetic studies that allow us to examine the effects of shared versus non-shared environment, as well as genes, on aggressive behaviors (Plomin, 1994). Only by including genetic effects in our developmental theories of aggressive behavior can we move this field of research.
Helen Tager-Flusberg, Daniela Plesa-Skwerer, in Developmental-Behavioral Pediatrics (Fourth Edition), 2009. Genetic Factors. Research on genetic influences relies exclusively on performance on intelligence tests that are typically used in behavioral genetics studies to provide estimates of the heritability of g, or general intelligence. Heritability is a technical construct that refers to the.
