In those who inherit two APOE3 alleles,
age of onset differs depending on which combination of the two 523 variants they also inherit.
Age of Onset Some studies indicate that both boys and girls tend to begin their antisocial careers around the age of fifteen, with the average
age of onset differing by no more than six months across genders.44 Other research, however, finds that females begin offending when they are younger than males are.45 Notably, gender differences in the age of onset tend to be most pronounced for serious or aggressive types of delinquency, while less serious problem behaviors, such as drug and alcohol - related offenses, have less gender - differentiated progressions.46

Our approach
differs from that adopted by Charlesworth [61], [62], who developed mathematical models to formalize the mutation accumulation hypothesis [63] that, together with the antagonistic pleiotropy hypothesis [3], [64], may be used to show how senescence can evolve by the accumulation

age of onset; such mutations enhance reproductive performance early in life but diminish survival late in life through physiological trade - offs.
