  • The genetic basis for behavioural traits is largely unknown. The overall aim of this thesis was to find genes with importance for behavioural traits related to fear and anxiety. Microarray analysis was used to screen expression profiles of brain regions important for emotional behaviour in dogs, wolves, foxes and mice. In a first experiment, dogs and their wild ancestors the wolves were compared. Our results suggested that directed selection for behaviour might have resulted in expression… CONTINUE READING
