This dissertation by Anna-Carin Karlsson investigates the genetic basis of domestication in chickens, focusing on the PMEL17 and TSHR genes. The research explores how mutations in these genes affect behavior, physiology, and gene expression in chickens, particularly those bred from the ancestral Red Junglefowl and the domesticated White Leghorn. The PMEL17 gene mutation influences plumage color and social behaviors, while the TSHR gene mutation impacts development, aggression, and reproductive responses. The study highlights the pleiotropic effects of these genes, suggesting their significant role in the domestication process. The work is intended for an academic audience interested in genetics, animal behavior, and evolutionary biology.

This thesis by Pia Katrine Løtvedt explores the genetic mechanisms underlying the domestication of chickens, focusing on the stress response in the Red Junglefowl and the domesticated White Leghorn. It examines differences in gene expression related to stress, behavior, and physiology, highlighting the attenuation of stress responses in domesticated chickens. The research identifies lower expression of genes for ACTH production and secretion in the pituitary and adrenal glands in domesticated breeds, suggesting an efficient feedback mechanism. Additionally, the thesis investigates the impact of hatching time on chicken phenotypes, revealing sex-specific effects on growth and behavior. These findings contribute to understanding domestication processes, early life experiences, and their implications for animal welfare and evolutionary biology.
