  1. 1. Screening of early root growth characteristics in seedlings of Nordic spring barley : utilization of hydroponics and GWAS for identification of QTLs and candidate genes for root traits

    Master-uppsats, SLU/Dept. Of Plant Breeding

    Författare :Karl-Johan Fabo; [2021]
    Nyckelord :spring barley; plant breeding; root growth; early vigor; seminor roots; GWAS; QTL; quantitative traits; quantitative genetics; marker-assisted breeding; hydroponics;

    Sammanfattning : In the Nordic countries, the cultivation of barley (Hordeum vulgare L.) has a long history, and as one of the major cereals in the world, barley is of global importance for food security. The world population is growing, which naturally will increase demands for agricultural outputs. LÄS MER

  3. 2. The role of RFX-target genes in neurodevelopmental and psychiatric disorders

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Abhishekapriya Ganesan; [2021]
    Nyckelord :;

    Sammanfattning : Neurodevelopmental disorders such as autism spectrum disorder (ASD) and psychiatric disorders, for example, schizophrenia (SCZ) represent a large spectrum of disorders that manifest through cognitive and behavioural problems. ASD and SCZ are both highly heritable, and some phenotypic similarities between ASD and SCZ have sparked an interest in understanding their genetic commonalities. LÄS MER

  4. 3. Genome-wide association studies on body weight and component traits in an intercross of two divergently selected chicken lines

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Yiwen Chen; [2021]
    Nyckelord :Genome-wide association study; Advanced Intercross Lines; Virginia chicken lines; artificial selection;

    Sammanfattning : Here we present the genome-wide association study of body weight at 8 weeks of age based onthe advanced intercross pedigree of two chicken lines gone through bi-directional selection.With improved marker density (~3M SNPs) and larger sample size (2667 individuals from F2-F15), 34 loci with suggestive significance are detected, of which 18 loci are novel, and the rest17 loci are consistent with the results of previous quantitative trait locus mapping studies onthis trait with smaller number of genetic markers and fewer individuals.

  5. 4. Changes in bull breeding during the years : a comparison between 1950 and 1980/90 century

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Moa Hagelberg; [2020]
    Nyckelord :Bulls; breeding; SNP; traits; decades; production; health; SLB; Holstein; SRB;

    Sammanfattning : Breeding on bulls have occurred during many decades in the same way as it has for dairy cattle. Both the sire and dams that are being used during the selection breeding have been tested through genomic selection to see their value for each trait, for the dams this has been started more recently than for the bulls.

  7. 5. Causality in Coexpression

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Carolina Barros; [2020]
    Nyckelord :bioinformatics; computational biology; genomics; causality; genetics; coexpression;

    Sammanfattning : One of the main goals of genetics has been to understand the link between genotype and phenotype. Using yeast (Saccharomyces cerevisiae) as our model organism, we take a closer look at the connection between genetic variation and gene expression to learn more about the mechanisms of gene regulation.
