1. 1. 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

3. 2. The Genetics of Speciation and Colouration in Carrion and Hooded Crows

   Författare :Jelmer Poelstra; Jochen Wolf; Hans Ellegren; Chris Jiggins; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; evolutionary genetics; genomics; birds; next-generation sequencing; pigmentation; pigmentation genetics; eumelanin; social selection; gene expression; population genomics; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Sammanfattning : A fundamental goal in biological research is to gain an understanding of the evolutionary processes and genetic elements that drive speciation. Genes responsible for reproductive isolation in young divergent lineages are particularly poorly known. In this thesis, the speciation genetics of carrion (Corvus (corone) corone) and hooded (C. LÄS MER

4. 3. Inferring demographic history and speciation of grouse using whole genome sequences

   Författare :Radoslav Kozma; Jacob Höglund; Jeff A. Johnson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Demographic history; speciation; effective population size; adaptation; willow grouse; red grouse; black grouse; rock ptarmigan; Tetraoninae; conservation genetics; climate change; PSMC; species distribution modelling; FOXP4; Agouti;

   Sammanfattning : From an ecological perspective, knowledge of demographic history is highly valuable because population size fluctuations can be matched to known climatic events, thereby revealing great insight into a species’ reaction to past climate change. This in turn enables us to predict how they might respond to future climate scenarios. LÄS MER

5. 4. Mapping Genes Affecting Phenotypic Traits in Chicken

   Författare :Susanne Kerje; Leif Andersson; Martien Groenen; Uppsala universitet; []
   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; Clinical genetics; 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

7. 5. Dissecting Phenotypic Variation in Pigmentation using Forward and Reverse Genetics

   Författare :Anders R Hellström; Uppsala universitet; []
   Nyckelord :Pigmentation; eumelanin; pheomelanin; knockout; Silver; SLC45A2; PMEL17; Sex-linked barring; CDKN2A; CDKN2B; ARF; chicken; Japanese quail; MEDICINE; MEDICIN; Molekylär genetik; Molecular Genetics;

   Sammanfattning : Coat color and patterning phenotypes have been extensively studied as a model for advancing our understanding of the relationship between genetic and phenotypic variation. In this thesis, genes of relevance for pigment cell biology were investigated. The dissertation is divided in two parts. LÄS MER
