  1. 1. Chicken domestication Effects of tameness on brain gene expression and DNA methylation

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Johan Bélteky; Linköpings universitet.; Linköpings universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Domestication greatly increases phenotypic variation in a short time span, with selection for a single phenotype and a plethora of associated phenotypic changes as an outcome of the process. The domestication process influences the underlying genomic architecture of a species, and the success and speed of the process is likely influenced by it. LÄS MER

  2. 2. Chicken Genomics - Linkage and QTL mapping

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Per Wahlberg; Uppsala universitet.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chicken; quantitative genetics; linkage map; QTL mapping; recombination; long-term selection; Z chromosome; selective sweep; SNP; NATURAL SCIENCES Biology Cell and molecular biology Genetics; NATURVETENSKAP Biologi Cell- och molekylärbiologi Genetik;

    Sammanfattning : This thesis presents results from genetic studies conducted in the chicken (Gallus gallus). The domestication of chicken is believed to have been initiated approximately 7,000 – 9,000 years ago in Southeast Asia. LÄS MER

  3. 3. Genetic and Genomic Studies in Chicken Assigning Function to Vertebrate Genes

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Jonas Eriksson; Uppsala universitet.; [2012]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chicken; BCO2; TSHR; COMTD1; Phenotypic variation; Domestication; Selective sweeps; Pigmentation; Molekylär genetik; Molecular Genetics;

    Sammanfattning : A major challenge in the post-genomic era is to understand how genome sequence variants (genotype) give rise to the enormous diversity observed in terms of morphology, physiology and behavior (phenotype) among living organisms. Domestic animals—with their tremendous phenotypic variation—are excellent model organisms for determining the relationships between genotype and phenotype. LÄS MER

  4. 4. Mapping Genes Affecting Phenotypic Traits in Chicken

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Susanne Kerje; Uppsala universitet.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; chicken; Quantitative Trait Loci; growth; egg production; epistasis; plumage colour; Extended black; MC1R; Dominant white; PMEL17; Genetik; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Clinical genetics; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Klinisk genetik;

    Sammanfattning : The purpose of gene mapping is to understand the underlying genetics of simple and complex traits like plumage colour and growth. This thesis is based on a cross between the wild ancestor of the modern chicken, the red junglefowl, and a White Leghorn line selected for high egg mass. LÄS MER

  5. 5. Neuropeptide Y Receptors in Human, Guinea pig and Chicken Cloning, in vitro Pharmacology and in situ Hybridization

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Sara Holmberg; Uppsala universitet.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; G-protein coupled receptor; neuropeptide Y; neuropeptide Y receptor; ortholog; chicken; guinea pig; mutagenesis; receptor computer modeling; mRNA in situ hybridization; Neurovetenskap; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Internal medicine Neurology; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Invärtesmedicin Neurologi; medicinsk farmakologi; Medical Pharmacology;

    Sammanfattning : Neuropeptide Y (NPY) is known to influence a vast number of physiological and behavioral processes such as vasoconstriction, circadian rhythms, feeding, anxiety and memory. Peptides of the NPY family bind to five different cloned G-protein coupled receptor subtypes (Y1, 2, 4-6). LÄS MER
