A quantitative genetic study on the proportion of males in tilapia
Lozano, Carlos (PhD Thesis;2011:63, Doctoral thesis, 2011)Early sexual maturation is one the main constraints in Tilapia farming since early breeding causes stunted growth and large size variability. To circumvent this problem all-male populations are used commercially, and ... -
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 ... -
Accuracy of genomic prediction of host resistance to salmon lice in Atlantic salmon (Salmo salar) using imputed high-density genotypes
Kjetså, Maria Henden; Ødegård, Jørgen; Meuwissen, Theodorus (Peer reviewed; Journal article, 2020) -
Accuracy of genomic selection for a sib-evaluated trait using identity-by-state and identity-bydescent relationships
Avitúa, Sergio Vela; Meuwissen, Theodorus; Luan, Tu; Ødegård, Jørgen (Journal article; Peer reviewed, 2015) -
Beyond large-effect loci: Large-scale GWAS reveals a mixed large-effect and polygenic architecture for age at maturity of Atlantic salmon
Sinclair-Waters, Marion; Ødegård, Jørgen; Korsvoll, Sven Arild; Moen, Thomas; Lien, Sigbjørn; Primmer, Craig R.; Barson, Nicola (Peer reviewed; Journal article, 2020)Background. Understanding genetic architecture is essential for determining how traits will change in response to evolutionary processes such as selection, genetic drift and/or gene flow. In Atlantic salmon, age at maturity ... -
Breeding for disease resistance against Edwardsiella ictaluri in Mekong striped catfish (Pangasianodon hypophthalmus)
Pham, Khoi Dinh (PhD Thesis;2020:77, Doctoral thesis, 2020)Bacillary necrosis (BN) is a disease caused by Edwardsiella ictaluri (E. ictaluri) that results in severe economic losses in farming of Mekong striped catfish (Pangasianodon hypophthalmus) in Vietnam. Genetic selection ... -
Case study development of a challenge test against Ewardsiella ictaluri in Mekong striped catfish (Pangasianodon hypophthalmus), for use in breeding
Pham, Khoi Dinh; Nguyen, Sang Van; Ødegård, Jørgen; Gjøen, Hans Magnus; Klemetsdal, Gunnar (Peer reviewed; Journal article, 2020) -
Direct and social genetic parameters for growth and fin damage traits in Atlantic cod (Gadus morhua)
Nielsen, Hanne Marie; Monsen, Brage Bråten; Ødegård, Jørgen; Bijma, Piter; Damsgård, Børge; Toften, Hilde; Olesen, Ingrid (Journal article; Peer reviewed, 2014) -
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) -
The effects of SNP-density and sample size on G-REML estimates of genetic and genic variance
Magwaba, Tapiwanashe (Master thesis, 2021) -
Genetic analyses of feed efficiency traits in pigs
Martinsen, Kristine Hov (PhD Thesis;2016:55, Doctoral thesis, 2017-12-12)The main objective of this thesis was to establish more detailed measurements feed efficiency in Norwegian Landrace and Norwegian Duroc in order to genetically improve this trait without negative consequenses for other ... -
Genetic analyses of meat, fat and carcass quality traits measured by rapid methods
Gjerliaug-Enger, Eli (PhD Thesis;2011:13, Doctoral thesis, 2011)The overall aim of this thesis was to analyse meat and fat quality traits using quantitative genetic methods. This study has demonstrated that it is possible to establish simple laboratory practices and high quality rapid ... -

Pham, Khoi Dinh; Ødegård, Jørgen; Van Nguyen, Sang; Gjøen, Hans Magnus; Klemetsdal, Gunnar (Journal article; Peer reviewed, 2020) -
Genetic correlations between challenge tested susceptibility to bacillary necrosis, caused by Edwardsiella ictaluri, and growth performance tested survival and harvest body weight in Mekong striped catfish (Pangasianodon hypophthalmus)
Pham, Khoi Dinh; Ødegård, Jørgen; van Nguyen, Sang; Gjøen, Hans Magnus; Klemetsdal, Gunnar (Peer reviewed; Journal article, 2020) -
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 ... -
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 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 ... -
