  1. 11. Studying genetics of leaf shape variation in Arabidopsis lyrata

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Carina Kvernes Macpherson; [2019]
    Nyckelord :Arabidopsis lyrata; Arabidopsis arenosa; leaf shape; RCO genes; genotype; phenotype; gene sequence variation;

    Sammanfattning : The relationship between leaf and its environment has resulted in a tremendous diversification of leaf shape within and between plants species, which is important to cope with the differing environmental conditions. Arabidopsis lyrata is a prime model plant that shows leaf shape variation within species and between related species. LÄS MER

  3. 12. Genetic diversity and hardiness in Scots pine from Scandinavia to Russia

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Jenny Olsson; [2019]
    Nyckelord :Pinus sylvestris; recolonization history; genetic diversity; cold hardiness; clinal variation;

    Sammanfattning : The postglacial recolonization of northern Europe supposedly originated from Western Europe and the Russian Plain, however, recent molecular and macrofossil-based investigations suggest that the history may be more complex than previously thought. This study aims to investigate the genetic diversity and population structure of Scots pine from Scandinavia to Russia to re-evaluate its recolonization history, and to examine whether the pattern of spatial genetic diversity has any adaptive significance.

  4. 13. Phenotypic variation for BOAS within four brachycephalic dog breeds : can good welfare be obtained?

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

    Författare :Ida Bertilsson; [2019]
    Nyckelord :BOAS; French bulldog; English bulldog; Pug; Boston Terrier; Conformation; welfare; phenotypic variation; respiration; brachycephaly; dog;

    Sammanfattning : Brachycephalic obstructive airway syndrome (BOAS) is an upper airway obstruction that was considered the most severe disorder identified according to the Generic Illness Severity Index for Dogs. The aim of this master thesis was to investigate the phenotypic variance correlated to BOAS in the Swedish population of four brachycephalic breeds; English Bulldog, French Bulldog, Pug and Boston Terrier and discuss their welfare implications.

  5. 14. Factors influencing variation in birth weight and its impact on later performance in Swedish Yorkshire pigs

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

    Författare :Paulina Wahlgren; [2018]
    Nyckelord :Piglets; birth weight; field performance test; backfat thickness; growth performance;

    Sammanfattning : The phenotypic variation in piglet birth weight caused by gender, birth parity number and litter size, and later how this variation in birth weight influenced growth rate until 100 kg and backfat thickness at 100 kg live weight were analysed in this study. Data on purebred Swedish Yorkshire pigs from 13 nucleus herds was the base for the analyses. LÄS MER

  7. 15. SVenX: A highly parallelized pipeline for structural variation detection using linked read whole genome sequencing data

    Master-uppsats, Lunds universitet/Examensarbeten i bioinformatik

    Författare :Vanja Börjesson; [2018]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Genomic rearrangements larger than 50 bp are called structural variants. As a group, they affect the phenotypic diversity among humans and have been associated with many human disorders including neurodevelopmental disorder and cancer. LÄS MER
