  1. 1. Estimating Variant Intolerance for Genes of Cattle

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

    Author : Simon Lanigan; [2024]
    Keywords : Genes; Cattle;

    Abstract : Cattle play a crucial role in providing nutrition and economic stability worldwide. Threats to their health, particularly infectious diseases, and genetic mutations, can have profound implications for both animal and human livelihoods. READ MORE

  3. 2. Systematics and the evolution of flower symmetry of Posoqueria (Rubiaceae)

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Sebastián Giraldo Gómez; [2023-06-14]
    Keywords : Posoquerieae; Cinchonoideae; Ixoroideae; Dialypetalanthoideae; Angiosperms 353; target capture; Hybpiper; Pollen Catapult Mechanism.;

    Abstract : The genus Posoqueria is a Neotropical group of shrubs and trees in the coffee family Rubiaceae. Posoqueria is phylogenetically poorly understood and presents several internal taxonomical difficulties. READ MORE

  4. 3. 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.

  5. 4. Relatedness and diversity in Swedish local chicken breeds using mitochondrial DNA D-loop sequences and SNP data

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

    Author : Esther Taiwo Afolabi; [2023]
    Keywords : chicken; genetic diversity; mtDNA d-loop; SNP; Swedish local chicken breeds;

    Abstract : Genetic diversity is the variation in genetic information carried by individuals within a species or population. This variability plays a crucial role in enabling species to adapt and survive in changing environments and is essential for evolutionary processes. READ MORE

  6. 5. Parentage Assignment using genetic markers in the common carp (Cyprinus carpio)

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

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

    Abstract : 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. READ MORE
