Genetics of resistance to photobacteriosis in gilthead sea bream (Sparus aurata) using 2b-RAD sequencing
Aslam, Muhammad Luqman; Carraro, Roberta; Bestin, Anastasia; Cariou, Sophie; Sonesson, Anna Kristina; Bruant, Jean-Sébastien; Haffray, Pierrick; Bargelloni, Luca; Meuwissen, Theodorus (Journal article; Peer reviewed, 2018)Background Photobacteriosis is an infectious disease developed by a Gram-negative bacterium Photobacterium damselae subsp. piscicida (Phdp), which may cause high mortalities (90–100%) in sea bream. Selection and breeding ... -
Genomic dissection of maternal, additive and non-additive genetic effects for growth and carcass traits in Nile tilapia

Genomic predictions including known QTL for reproduction traits in swine
Häfliger, Irene (Master thesis, 2016)Breeding values are the fundament on which the selection of the next generation is based on and should therefore be as reliable as possible. The implementation of marker-assisted selection (MAS), where major genes are ... -
Genomic selection strategies to improve maternal traits in Norwegian White Sheep
Lillehammer, Marie; Sonesson, Anna Kristina; Klemetsdal, Gunnar; Blichfeldt, Thor; Meuwissen, Theodorus (Peer reviewed; Journal article, 2020) -
Genotype calling of triploid offspring from diploid parents
Grashei, Kim Erik; Ødegård, Jørgen; Meuwissen, Theodorus (Peer reviewed; Journal article, 2020) -
GWAS identifies genetic variants associated with omega-3 fatty acid composition of Atlantic salmon fillets
Horn, Siri Storteig; Ruyter, Bente; Meuwissen, Theodorus; Moghadam, Hooman; Hillestad, Borghild; Sonesson, Anna Kristina (Peer reviewed; Journal article, 2020)The objective of this study was to identify genetic variants associated with long-chain omega-3 fatty acid content in Atlantic salmon muscle, in order to identify genes underlying the genetic variation in these traits, by ... -
Identification of Genomic Variants Causing Variation in Quantitative Traits: A Review
Meuwissen, Theodorus; Hayes, Ben; MacLeod, Iona; Goddard, Michael (Peer reviewed; Journal article, 2022) -
Improved dairy cattle mating plans at herd level using genomic information
Bérodier, Marie; Berg, Peer; Meuwissen, Theodorus; Boichard, Didier; Brochard, Mickaël; Ducrocq, Vincent (Peer reviewed; Journal article, 2021) -
Individual differences in EPA and DHA content of Atlantic salmon are Associated with gene expression of key metabolic processes
Horn, Siri Storteig; Sonesson, Anna Kristina; Krasnov, Aleksei; Moghadam, Hooman; Hillestad, Borghild; Meuwissen, Theodorus; Ruyter, Bente (Journal article; Peer reviewed, 2019) -
Introgression of a major QTL from an inferior into a superior population using genomic selection
Ødegård, Jørgen; Sonesson, Anna Kristina; Yazdi, Hossein; Meuwissen, Theodorus (Peer reviewed; Journal article, 2009)Conclusion: Substantial differences between introgression programs using classical and genomic selection were observed, and the former was generally inferior with respect to both genetic gain and the ability to preserve ... -
Large-scale genomic prediction using singular value decomposition of the genotype matrix
Ødegård, Jørgen; Indahl, Ulf Geir; Stranden, Ismo; Meuwissen, Theodorus (Journal article; Peer reviewed, 2018) -
Level-biases in estimated breeding values due to the use of different SNP panels over time in ssGBLUP
Nordbø, Øyvind; Gjuvsland, Arne Bjørke; Eikje, Leiv Sigbjørn; Meuwissen, Theodorus (Peer reviewed; Journal article, 2019)Abstract Background: The main aim of single-step genomic predictions was to facilitate optimal selection in populations consisting of both genotyped and non-genotyped individuals. However, in spite of intensive research, ... -
Modeling feed intake and feed efficiency along the lactation curve of Norwegian Red Dairy Cattle
Obari, Christiana Onyinoyi (Master thesis, 2021)Including feed efficiency into breeding goals could be a key in ensuring sustainable dairy cattle production as selection could be based on how efficient a cow is in terms of what it consumes and produces all through the ... -

Optimal Contribution Selection applied to the Norwegian Cheviot Sheep population
Kjetså, Maria Henden (Master thesis, 2016-08-18)Managing inbreeding is essential for all breeding work, especially in small populations. Optimal Genetic Contribution (OCS) is a selection method that restricts inbreeding while maximizing genetic gain. The aim of this ... -
