  1. 1. The Valeriana officinalis aggregate in Sweden. A preliminary study.

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Daniel Bäck; [2023-06-30]
    Nyckelord :;

    Sammanfattning : Common valerian (Valeriana officinalis L.) is a species of flowering plants native to Europe, the roots of which have been used in folk medicine for centuries. But due to high diversity in morphology and chromosome numbers, different populations in V. LÄS MER

  3. 2. Fitnesskomponenter hos honor av Drosophila melanogaster : Med alternativa alleler av en potentiell sexuellt antagonistisk gen

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Maja Högström; [2023]
    Nyckelord :Drosophila melanogaster; fruit fly; intralocus sexual conflict; antagonistic genes; Drosophila melanogaster; bananfluga; antagonistiska gener; sexuellt antagonistiska gener;

    Sammanfattning : Anisogami och sexuella konflikter kan vara grunden till flera fall av könslig dimorfism. Intralokus sexuell konflikt uppstår när alleler vid ett genetiskt lokus har en antagonistisk effekt på fitness hos hanar och honor. Helgenomstudier har pekat ut flera sexuellt antagonistiska kandidatgener hos Drosophila melanogaster. LÄS MER

  4. 3. Parentage Assignment using genetic markers in the common carp (Cyprinus carpio)

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

    Författare :Sven Kristian Feddersen; [2023]
    Nyckelord :single nucleotide polymorphism; Parentage Assignment; aquaculture; genetic markers;

    Sammanfattning : This study investigated the effect of varying single nucleotide polymorphisms (SNPs) marker density, error threshold selection, and different SNP selection strategies on parentage assignment accuracy in carp populations. Using a marker set of 15,615 SNPs, we found a positive correlation between the quantity of SNP markers and the accuracy of parentage assignments, consistent with existing literature. LÄS MER

  5. 4. Exploring the genetic cause of myotonic dystrophy in horses

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

    Författare :Thomas Simon; [2023]
    Nyckelord :genetics; bioinformatics; myotonic dystrophy; horses; variant analysis;

    Sammanfattning : Myotonic Dystrophy (MD) is an inherited neuromuscular disorder that leads to a wide range of clinical signs including stiffness, abnormal muscle relaxation, and muscle atrophy or hypertrophy. Affected muscles develop a prolonged contracture in response to percussion of the muscle and show waxing and waning complex repetitive discharges in electromyography (EMG). LÄS MER

  7. 5. SubKluster: Novel method to bin scaffolds from cereal genomes into subgenomes using substring frequency analysis

    Master-uppsats, Lunds universitet/Examensarbeten i bioinformatik

    Författare :Victor Kalbskopf; [2023]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : The genome of the Belinda variety of the hexaploid oat (Avena sativa) has recently been sequenced and assembled. This project aims to improve the assembly by clustering the thousands of scaffolds into their three ancestral subgenomes using Principle Component Analysis (PCA) of kmer and repeat-element frequencies.
