  1. 1. Domestication Effects on the Stress Response in Chickens : Genetics, Physiology, and Behaviour

    Författare :Amir Fallahshahroudi; Per Jensen; Frank Albert; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Animal domestication; stress response; gene expression; QTL; eQTL;

    Sammanfattning : Animal domestication, the process where animals become adapted to living in proximity to humans, is associated with the alteration of multiple traits, including decreased fearfulness and stress response. With an estimated population of 50 billion, the domesticated chicken is the most populous avian species in the world. LÄS MER

  3. 2. Genetics of equine insect bite hypersensitivity and genetic diversity in horses

    Författare :Merina Shrestha; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Genetic variation contributing to the phenotypic variation was utilized in this thesis to understand the genetic background of a complex trait IBH, and to understand genetic diversity and relationships between various horse populations. IBH is the most common skin allergic disorder in horses, caused by bites of midges, predominantly Culicoides species. LÄS MER

  4. 3. Monogenic Traits Associated with Structural Variants in Chicken and Horse : Allelic and Phenotypic Diversity of Visually Appealing Traits

    Författare :Freyja Imsland; Leif Andersson; Gabriella Lindgren; Kerstin Lindblad-Toh; Eiríkur Steingrímsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Structural variation; Pigmentation; Domestication; Equids; MNR2; CCDC108; STX17; TBX3; Grey; Dun; non-dun; Rose-comb; Chicken; Genetic mapping; Phenotyping; Molekylär genetik; Molecular Genetics;

    Sammanfattning : Domestic animals have rich phenotypic diversity that can be explored to advance our understanding of the relationship between molecular genetics and phenotypic variation. Since the advent of second generation sequencing, it has become easier to identify structural variants and associate them with phenotypic outcomes. LÄS MER

  5. 4. Conservation Genetics of Scandinavian Wolverines

    Författare :Eva Hedmark; Hans Ellegren; Lisette Waits; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; carnivores; conservation; genetic monitoring; molecular sexing; non-invasive genetic techniques; parentage analysis; tanning; Genetik; Gulo gulo; Genetics; Genetik;

    Sammanfattning : In this thesis, genetic methods for individual identification and sex determination of wolverines from non-invasive samples were developed and applied in genetic monitoring of Scandinavian wolverine populations. Paternity and mating system of wolverines were studied by combining genetic analysis with telemetry data. LÄS MER

  7. 5. Population structure and pathogenicity evolution of Phytophthora infestans affects epidemiology and management of late blight disease

    Författare :Anne Njoroge; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Sound management of late blight, the disease caused by the notorious oomycete pathogen Phytophthora infestans (Mont.) de Bary, is dependent on the pathogen’s population biology. However, for P. LÄS MER
