  1. 21. Consistency and heritability of personality in red junglefowl (Gallus gallus) : Applying scientific research methods when teaching biology

    University essay from Biologi

    Author : Josefin Kvarnström; [2013]
    Keywords : Boldness; Chicken; Exploration; Fearfulness; Scientific approach and education; Risk-taking;

    Abstract : Observations of consistency in behavioural responses in animals suggest that animals have personality, a term previously mainly used when describing humans.

    Keywords : activity; exploration; development; bird; behaviour;

    Abstract : Many studies have been performed on animals to study their behavior, but not as many on the development of behavior, and not yet on chickens.

    Keywords : Domestication; Chicken; Fear; Dominance; Thyrotropin; Thyroid stimulating hormone receptor; TSHR;

    Abstract : Thyroid hormones are well known important to be in development and growth in birds and that signaling of thyrotropin (TSH) regulates the photo induced seasonal reproduction. A mutation at the thyroid stimulating hormone receptor (TSHR) gene in domestic breeds of chicken could be involved in the release of the photoperiodic regulation. READ MORE
