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

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

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

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

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

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

    Abstract : 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). READ MORE

  4. 3. Pride and prejudice : extra-group paternity in lions and the effects of marker density on kinship and relatedness estimates

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

    Author : Julia Jansson; [2017]
    Keywords : lion; mating structure; extra-group paternity; Single Nucleotide Polymorphism SNP ; marker density; panthera leo;

    Abstract : The development effective high-throughput sequencing techniques has allowed further insight to the mating systems of wild animal populations and challenged our perception that reproductive behaviour can be predicted from social structure. A recent study of lions (Panthera leo) in Etosha National Park, Namibia, found evidence of extra-group paternity (EGP) which has never before been confirmed among lions. READ MORE

  5. 4. Investigation of genetic correlation among traits using massive SNP genotype in German Holstein population

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

    Author : Esmaeil Amiri; [2010]
    Keywords : additive genetic variance; genetic correlation; dairy cattle; genotypes; milk yield; somatic cell count;

    Abstract : The aims of this study were to demonstrate the genomic architecture of quantitative traits using Illumina BovineSNP50 Beadchip as well as the identification of chromosomes or SNPs affecting multiple traits in German Holstein population. For this research, a total of 2333 German Holstein bulls were genotyped for 54,001 SNPs. READ MORE

  6. 5. Selection on DRD4 haplotypes in a natural great tit population in relation to personality

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

    Author : Bimal Chakkingal Bhaskaran; [2009]
    Keywords : DRD4; dopamine receptor; great tit; early exploratory behaviour;

    Abstract : Variations in neurotransmitter-related genes are reported to be associated with personality traits among humans. One of the genes, the dopamine receptor (Drd4) gene showed a relation with novelty-seeking behaviour or curiosity traits. READ MORE
