Race X Behavior

Filed under: Dogs care — Tags: , , , , , — Cynara @ 9:39 am

Will it be possible the behavior characteristic, how the aggressiveness, be transmitted for the following generation? 
In the same way that morphologic characteristics can be inherited of last generations, neurophysiological characteristics also can. Therefore, the genetic predisposition for several behavior problems can justify a possible association between aggressiveness and race of the dog. 
Such relationship can be justified with differences in the neurotransmitter levels or in the efficiency of their receivers in the Central Nervous System, favoring, or no, the appearance of problems as aggressiveness or anxiety. 
Some goods associate structural alterations in the brains of aggressive dogs and no aggressive. For instance, there is an increase of the number of receivers for androgenic in the tonsil in aggressive male dogs compared the no aggressive. There is also increase in the number of receivers in the front cortex, hippocampus and thalamu of the aggressive dogs compared to the no aggressive, etc. 
Those aspects, among other, they could find the favorable arguments to the association between race and aggressiveness, however it is not still possible to answer to the question a direct association there are been between aggressiveness and race.
