Genes basis of temperament and personality

According to genetics of behavior data contribution of genetic factors in d ifference of human temperament characteristics is 30-60 %, more over,temper ament features depend on summary influence or interaction of many genes wit h little effects. From the middle of 90-s concrete genes responsible for in dividual differences in temperament features are searched. It became possib le due to exploration of genes which encode albumens with already known fun ctions in brain biochemical processes,as well as to creation of methods tha t allow to define relatively easy which gene's allele forms contain genotyp e of this or that person. As of now reliable and reproduced results in inve stigation of genes basis of temperament: are not yet obtained. One of the m ost perspective lines of investigation is search of associations between 1) genes involved in functioning of dofamin system,and those dynamic peculiar ities of behavior which are connected with activity and sociability/estrang ability, 2) serotonin transporting gene and anxiety,3) tryptophan hydrocsil azagene and aggression.
