The accuracy of genomic prediction by singular value decomposition of the genotype matrix
Ayres, Lucas Lima (Master thesis, 2022)Increasing the order of the genotype matrix by augmenting the number of animals or genetic markers represents a computational challenge for genomic selection. The objective of this study is to evaluate the effect of the ... -
Adjusting for heterogeneity of experimental data in genetic evaluation of dry matter intake in dairy cattle.
Uddin, Md. Elias; Meuwissen, Theo; Veerkamp, Roel F (Journal article; Peer reviewed, 2017) -
Application of a Bayesian dominance model improves power in quantitative trait genome-wide association analysis
Bennewitz, Jörn; Edel, Christian; Fries, Ruedi; Meuwissen, Theo; Wellmann, Robin (Journal article; Peer reviewed, 2017) -
Economic values for lean meat and fat efficiency in Norwegian Landrace nucleus pig population
Martinsen, Kristine Hov; Olsen, Dan; Ødegård, Jørgen; Meuwissen, Theo (Journal article; Peer reviewed, 2017) -
Estimates of missing heritability for complex traits in Brown Swiss cattle
Roman-Ponce, Sergio-Ivan; Samore, Antonia B; Dolezal, Marlies A; Bagnato, Alessandro; Meuwissen, Theo (Journal article; Peer reviewed, 2014) -
Genetic diversity in five chicken lines from the Norwegian live poultry gene bank
Brekke, Cathrine (Master thesis, 2017)Since 1995, there has been no active breeding of commercial egg layers in Norway. The last active breeding lines, as well as other breeds of conservation value are conserved in the Norwegian live poultry gene bank. The aim ... -
Genetic effects of fatty acid composition in muscle of Atlantic salmon
Horn, Siri Storteig; Ruyter, Bente; Meuwissen, Theo; Hillestad, Borghild; Sonesson, Anna Kristina (Journal article; Peer reviewed, 2018) -
Genetic variation and management of the Norwegian horse breeds
Olsen, Hanne Fjerdingby (PhD Thesis;2011:05, Doctoral thesis, 2011)The Norwegian horse breeds suffer from strong competition in the market from imported, specialized breeds. Decreasing population sizes, especially for the Fjord, the Døle and the Nordland/Lyngen, and risk of rapid accumulation ... -
The genetics of omega-3 fatty acids in fillets of Atlantic salmon (Salmo salar L.)
Horn, Siri Storteig (Doctoral thesis, 2019)Decreasing contents of the omega-3 fatty acids EPA and DHA in farmed Atlantic salmon reduces the nutritional value for consumers and influences physiological processes in the fish. Most studies of physiological omega-3 ... -
Genomic methods in breeding programs: Parental assignment, triploid genomics and case-parental control modelling
Grashei, Kim Erik (Phd Thesis;2021:7, Doctoral thesis, 2021)The use of high-density single nucleotide polymorphism (SNP) genotypes enables us to perform highly accurate parentage assignment. However, dependence between loci often results in using a subset of the data to obtain ... -
Genomic prediction based on runs of homozygosity
Luan, Tu; Yu, Xijiang; Dolezal, Marlies; Bagnato, Allessandro; Meuwissen, Theo (Journal article; Peer reviewed, 2014) -
Genomic prediction in an admixed population of Atlantic salmon (Salmo salar)
Ødegård, Jørgen; Moen, Thomas; Santi, Nina; Korsvoll, Sven Arild; Kjøglum, Sissel; Meuwissen, Theo (Journal article; Peer reviewed, 2014) -
Genomic prediction using high-density and whole-genome sequence genotypes
Kjetså, Maria Valkeneer (Phd Thesis;2022:33, Doctoral thesis, 2022)The main objective of this thesis was to investigate genomic prediction methods for high-density and whole-genome sequence genotypes, with emphasis on traits that may have difficulties achieving a high prediction accuracy ... -

Zhou, L; Heringstad, Bjørg; Su, G; Guldbrandtsen, B; Meuwissen, Theo; Svendsen, Morten; Grove, Harald; Nielsen, US; Lund, MS (Journal article; Peer reviewed, 2014) -
Imputation to and use of whole genome sequencing for fine mapping and genomic predication in Atlantic salmon
Onabanjo, Olumide Victor (Master thesis, 2023)Sea lice (Lepeophtheirus salmonis) infestation of Atlantic salmon (Salmo salar) is a significant challenge facing the Aquaculture industry. This parasite is known to be resistant to chemical control. Previous research that ... -

Maternal, dominance and additive genetic effects in Nile tilapia; influence on growth, fillet yield and body size traits
Joshi, Rajesh; Woolliams, John Arthur; Meuwissen, Theo; Gjøen, Hans Magnus (Journal article; Peer reviewed, 2018)There are only few studies of dominance effects in non-inbred aquaculture species, since commonly used mating designs often have low power to separate dominance, maternal and common environmental effects. Here, a factorial ... -
