• In certain systemes of the organism the reinforcement of genetically loosely determined traits is necessary and it is realised under the effect of the actual (new) inner and outer milieu perinatally, mostly after birth. In this period the sexual, hormonal, enzyme, and behavioral imprinting are taking place and this is the time of closing of the self-nonself discrimination. The program stored in the genes is selected and activated in that time, what makes the effect of perinatal adjusting (imprinting) practically equal with the genetic determination. Because of this, rather difficult is to differentiate between the effects of imprinting and genes. In the critical period of adjusting (imprinting) chemical mate-rials disparate from the normal ones, (however effective and able to bind to receptors) and faulty actions (in the case of behavioural imprinting) can cause faulty imprinting, whose effects are measurable for life. The possibility (and importance) of the faulty imprintings is growing nowadays.
