  1. 21. De novo SNP Discovery in the Spotted Hyena (Crocuta crocuta)

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Amber Mertens De Vry; [2021]
    Keywords : single nucleotide polymorphism; SNP; spotted hyena; Crocuta crocuta; relatedness; genetic monitoring;

    Abstract : Relatedness studies of wild populations using reliable high-quality genetic markers enhance our understanding of a species’ behavior and ecology. Spotted hyenas (Crocuta crocuta) have a matriarchal social structure, unique amongst carnivores. READ MORE

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

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

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

    Abstract : 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.

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

    University essay from SLU/Dept. of Animal Breeding and Genetics

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

    Abstract : 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.
