Theoretically what this means is that in order to express this gene, in a violent way, very early on, before puberty, you have to be involved in something that is really traumatic, not a little stress, not being spanked or something, but really seeing violence, or being involved in it, in 3D.
Teóricamente, lo que significa es que para que el gen se exprese de una manera violenta, muy pronto, antes de la pubertad, se ha de haber pasado por algo realmente traumático, no un poco de estrés, nada de que les peguen o algo así. Sino ver violencia de verdad, o estar envuelto en ella, en 3D.
