Associations between temperament and gene polymorphisms in the brain dopaminergic system and the adrenal gland of sheep.

Physiology & behavior - 1 Jan 2016

Qiu Xiaoyan, Ledger Jason, Zheng Chen, Martin Graeme B, Blache Dominique

Abstract excerpt

Sheep of calm or nervous temperament differ in their physiological (cortisol secretion) and behavioural (motor activity) responses to stressors, perhaps due to variation in genes that regulate glucocorticoid synthesis or brain dopamine activity. Using ewes that had been selected over 20 generations for nervous (n=58) or calm (n=59) temperament, we confirmed the presence of a polymorphism in a gene specifically...
