  1. 1. Exploration of the hereditary cause of sex ratio distortion in horses

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

    Författare :Susan Ott; [2021]
    Nyckelord :Sex ratio; horse; selfish genetic elements; meiotic drive; Icelandic horse; Standardbred horse; Coldblooded trotters; heritability; Trivers-Willard hypothesis; pedigree data;

    Sammanfattning : Even sex ratios are seen as evolutionarily stable and are maintained by a selection against a skewed sex ratio. However, sometimes sex ratios at birth are skewed towards one sex. Reasons for this phenomenon are often unknown. LÄS MER

  2. 2. Genetic background of temperament traits in standardbred trotters

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

    Författare :Paulina Berglund; [2021]
    Nyckelord :temperament; standardbred trotter; heritability; low-pass whole genome sequencing;

    Sammanfattning : The genetic background of temperament traits in horses has been subject for research for many years to obtain understanding of domestication, breed differences and welfare. Previous studies have found heritabilities ranging from low to moderate for temperament. LÄS MER

  3. 3. Is a potential regulatory region in the vicinity of EDN3 linked to the performance in Standardbred horses?

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

    Författare :Linda Novácková; [2018]
    Nyckelord :performance; standardbred; EDN3; endothelin-3;

    Sammanfattning : Standardbred horses (SBs) are used in harness racing. Their common breeding history with Coldblooded trotters (CBTs) led us to the hypothesis, that the same region associated with race performance in CBTs, may be linked to the performance of SBs as well. EDN3 SNP (g.22:45748491C>T), was found to be associated (p. LÄS MER

  4. 4. The role of myostatin in Coldblooded trotter harness racing performance

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

    Författare :Katrine Petäjistö; [2016]
    Nyckelord :horse; myostatin; Coldblooded trotter; harness racing; performance;

    Sammanfattning : Myostatin (MSTN) är en gen som begränsar massan av skelettmuskler genom att reglera både antalet och tillväxten av muskelfibrer. Mutationer i den här genen resulterar i en dubbeltmusklad fenotyp noterad hos ett flertal boskapsraser, hundar och människor. LÄS MER

  5. 5. Association of the DMRT3 nonsense mutation with performance in Coldblooded trotters

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Animal Breeding and Genetics

    Författare :Chameli Lawrence; [2016]
    Nyckelord :DMRT3; horse; trotters; genetic; genes; locomotion pattern; racing performance; harness racing;

    Sammanfattning : In previous studies, a nonsense mutation in the gene doublesex and mab-3 related transcription factor 3 (DMRT3) was discovered to have a major influence on gait ability in horses. The mutation is permissive for the ability to perform alternate gaits, such as pace and tölt and has also been shown to have a favorable effect on speed capacity and harness racing performance in Coldblooded and Standardbred trotters.
