  1. 1. Analysis of relatedness and genetic diversity in Swedish sheep breeds using medium density (50K) SNP data

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

    Författare :Krishani Devika Wijesinghe Sinhalage; [2023]
    Nyckelord :sheep; genetic diversity; population structure; inbreeding; runs of homozygosity; coat colour; MC1R;

    Sammanfattning : The local Swedish sheep breeds belong to a group of sheep breeds known as North European short-tailed sheep breeds. Evaluation of genetic diversity, relatedness, and population structure of local breeds offers crucial metrics to prevent inbreeding depression, genetic erosion, and crossbreeding between locally adapted and exotic sheep breeds since these occurrences can have detrimental effects and ultimately lead to extinction.

  3. 2. Detecting structural variants in the DNA of the inbred Scandinavian wolf

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Lars Huson; [2023]
    Nyckelord :animal; animal population; bioinformatics; biological sciences; biology; Canis lupus; CNV; conservation genetics; conservation genomics; copy-number variation; DNA; endangered population; endangered species; evolution; evolutionary biology; extinction; genetic diversity; genetics; genetic variation; genomes; genomics; grey wolf; inbreeding; inbreeding depression; indel; mutation; pedigree; population genetics; population genomics; Scandinavia; smoove; snakemake; structural variant; SV; wolf; wolves;

    Sammanfattning : Only 40 years ago, just three individuals made the journey from Finland/Russia to found the current wolf population in the southwest of Sweden. This population, that to this date descends from less than 10 founders, has a substantial increased extinction risk due to inbreeding. LÄS MER

  4. 3. Genomic diversity analysis in the Swedish Landrace Goat

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

    Författare :Bernadett Hegedüs; [2022]
    Nyckelord :Swedish Landrace Goat; genetic diversity; inbreeding; runs of homozygosity; ; population structure;

    Sammanfattning : There are four goat breeds present in Sweden. However, no genetic studies were dedicated to investigating the genetic diversity in these breeds. This thesis therefore aims to describe the population structure and the level of inbreeding in the goat breed with the largest population number, the Swedish Landrace goat. LÄS MER

  5. 4. Inavelsgrad i stängda stamböcker : en high density SNP analys av fem svenska fårraser

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Sophie Olsson; [2022]
    Nyckelord :Inavel; high density SNP; ROH; effektiv populationsstorlek; svenska fårraser; stambok;

    Sammanfattning : Med hjälp av high density SNP, en metod för att kartlägga basparspolymorfism, undersöktes släktskap och inavelsgrad hos fem svenska fårraser. Inavelsgraden undersöktes med avseende på heterozygoti samt antal och längd för s.k. runs of homozygosity (ROH). LÄS MER

  7. 5. Genetic assessment of plant material for studies of the genetic causes to female biased sex ratios in Salix viminalis L.

    Kandidat-uppsats, SLU/Department of Plant Biology (from 140101)

    Författare :Amela Kujović; [2016]
    Nyckelord :sex ratio; willows; dioecy; white seeds; homozygosity; inbreeding;

    Sammanfattning : Biased sex ratios are highly common among dioecious plants. Salix viminalis is a dioecious tree or a woody shrub that has an overall female biased sex ratio. LÄS MER
