    Abstract : Aquatic organisms are constantly at risk of being exposed to potentially harmful chemical compounds of natural or anthropogenic origin. Biological life can for instance respond to chemical stressors by changes in gene expression, and thus, certain gene transcripts can potentially function as biomarkers, i.e. READ MORE

  4. 22. Dissecting the genetics of athletic performance and conformation traits in horses

    Author : Maria Rosengren; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The overall aims of this thesis were to investigate the genetics of athletic performance and the level of inbreeding in Coldblooded trotters, as well as the genetics of conformation traits in Icelandic horses. In paper I, genomic-based inbreeding coefficients in Coldblooded trotters were estimated and compared with pedigree-based coefficients. READ MORE

  5. 23. Genomic selection and genome-wide association studies to dissect quantitative traits in forest trees

    Author : Biyue Tan; Pär K. Ingvarsson; Björn Sundberg; Harry X. Wu; Dario Grattapaglia; Xiao-Ru Wang; Leopoldo Sanchez; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Genomic prediction; genome-wide association study; additive effects; dominance effects; epistasis effects; realized relationship matrix; Eucalyptus grandis; Eucalyptus urophylla;

    Abstract : The convergence of quantitative genetics of complex traits with genomic technologies is quickly becoming an innovative approach to explore fundamental genetic questions and also have practical consequences for implementations in tree breeding. In this thesis, I used genomic selection and genome-wide association studies (GWAS) to dissect the genetic basis of quantitative traits, i. READ MORE

  6. 24. Mapping and functional characterization of candidate genes and mutations for chicken growth : an approach combining computational genetics and bioinformatics

    Author : Muhammad Ahsan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Knowledge of the genetics related to growth is important for breeding chickens with the desired traits of rapid and efficient growth. A long-term selection experiment in the domestic chicken (Gallus gallus) has resulted in two highly divergent lines selected for juvenile body weight. READ MORE

  7. 25. Type 2 Diabetes Genes Contributing to Insulin Secretion Defects

    Author : Charlotte Granhall; Genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sekretion; Endokrinologi; exocytosis; GK rat; NIDDM1I; genetics; gene expression; quantitative trait analysis; Sorcs1; Adra2a; Endocrinology; diabetology; insulin secretion; diabetologi; secreting systems; Type 2 diabetes;

    Abstract : Type 2 diabetes is caused by a combination of environmental and inherited factors influencing the progression of insulin resistance and impaired insulin secretion leading to chronically elevated blood glucose levels. The aim of this thesis was to functionally and genetically characterise the species-conserved diabetes locus Niddm1i of the GK rat encoding hyperglycaemia and defect insulin secretion. READ MORE
