The use of twin studies is useful in researching in to this field as if a greater similarity is shown in monozygotic twins (Mz, identical, share 100% DNA)than dyzygotic twins (Dz, non-identical, share 50% DNA) then it can be argued that nature overrides nurture in aggressive behaviour.
Later studies by Guo and colleagues investigated MAOA variants in 2500 American boys in grades 7 to 12, and demonstrated a genetic basis for severe aggressive behavior seen at school.
