  2. 1. Genetic Analysis of Quantitative Traits Using Domestic Animals : A Candidate Gene and Genome Scanning Approach

    Author : Hee-Bok Park; Leif Andersson; Stefan Marklund; Robert Fredricksson; Holger Luthman; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Domestication; horse; pig; chicken; quantitative traits; candidate gene; genome scan; PRKAG3; MC4R; selection experiment; growth; correlated response; metabolic disorders; Quantitative Trait Loci; linkage; single nucleotide polymorphisms; Genetik; Clinical genetics; Klinisk genetik;

    Abstract : Domestication has led to genetic changes that affect quantitative traits in farm animals. Both candidate gene analysis using association tests and genome scans based on linkage analysis have been performed to understand the molecular basis underlying quantitative genetic variation in horses, pigs and chickens.

  4. 2. From wolf to dog: Behavioural evolution during domestication

    Author : Christina Hansen Wheat; Hans Temrin; Clive Wynne; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Domestication syndrome; behavioural evolution; behaviorual ontogeny; correlated traits; sociability; playfulness; aggression; fear; Canis familiaris; Canis lupus; artificial selection; etologi; Ethology;

    Abstract : Biologists since Darwin have recognized that domestication, where species are selected to live in human-controlled environments, exerts strong selection on organisms and dramatically impacts their evolutionary trajectories. Across domesticated mammal species, characteristic morphological, physiological and behavioural changes occur simultaneously, as correlated traits, a phenomenon known as the domestication syndrome.

  5. 3. On the importance of inflammation for personality traits and psychiatric morbidity

    Author : Petra Suchankova; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; inflammation; C-reactive protein; complement factor H; S100B; receptor for advanced glycation end products; polymorphism; gene expression; personality traits; suicidal behaviour; schizophrenia; depression; Flinders sensitive line;

    Abstract : Background: Pro-inflammatory mediators have been implicated in processes that could be both beneficial and toxic to cells in the brain. On the one hand balanced levels of these mediators favour e.g. READ MORE

  6. 4. Correlated selection responses in animal domestication : the behavioural effects of a growth QTL in chickens

    Author : Anders Wirén; Per Jensen; Elena Jazin; Linköpings universitet; []
    Keywords : ;

    Abstract : Studying animal domestication offers an opportunity to understand the mechanisms of evolution. Domestication is associated with a change in selection pressures; selection for production traits is introduced, and animals are faced with larger and denser social groups. READ MORE

  7. 5. Interaction between dispersal and behavioural syndromes - empirical approach in a fragmented population of passerine birds

    Author : Gregory Daniel; Blandine Doligez; Lars Gustafsson; Thierry Boulinier; Uppsala universitet; []
    Keywords : dispersal; behavioural syndromes; heritability; personality traits; neophobia; aggressiveness; risk-taking behaviour; collared flycatcher; Ficedulla albicollis; dispersion; syndromes comportementaux; héritabilité; traits de personnalité; néophibie; aggressivité; prise de risque; gobemouche à collier; Ficedulla albicollis; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Abstract : Dispersal is a key life history trait for ecological and evolutionary processes in wild populations. The latest research has particularly focused on the correlation between behavioural traits and dispersal, in order to emphasize the existence of behavioural syndromes of dispersal, and on the estimation of the genetic basis of the dispersal behaviour.
