Genetisk variasjon og clusteranalyse på bakgrunn av slektskapsdata hjå dølahest
(Master thesis, 2017)Formålet med denne oppgåva var å analysere genetisk variasjon hjå dølahesten, å sjå på slektskapsstruktur i rasen ved hjelp av clusteranalyse, samt å sjå på moglegheiter for gode strategiar for berekraftig avl i framtida. ... -
Genetisk variasjon og fargegenetikk hos fjordhest
(Master thesis, 2017)Hensikten med denne oppgaven var å beregne innavl for dagens fjordhestpopulasjon. Populasjonen i Norge er ikke stor, og det har vært en trend i lave bedekningstall og lavt antall fødte føll de siste årene. Datasettet brukt ... -
Genetiske analyser av tilvekstegenskaper hos norske og amerikanske foredlingsbesetninger av landsvin
(Master thesis, 2012-10-18)Genetiske analyser av ulike tilvekstegenskaper ble gjort med bakgrunn i et rådatasett fra to besetninger i USA og et datasett fra Norsvins foredlingsbesetninger fra 2011. Filen med rådata fra norske landsvin i USA besto ... -
Genetiske sammenhenger mellom drektighetslengde og kalvingsegenskaper i Norsk Rødt Fe (NRF)
(Master thesis, 2012-06-21)Det er så langt ikke gjort noen genetisk analyse av drektighetslengde i Norsk Rødt Fe (NRF), så målet med oppgaven var å estimere arvegrader og genetiske korrelasjoner for drektighetslengde, dødfødsler, kalvingsvansker og ... -
Genome editing for sustainability: Improving host resistance to combat late blight in potato and sea lice in Atlantic salmon
(Master thesis, 2021)Few species are as central to Norwegian society and culture as the potato and the Atlantic salmon. Yet these industries face considerable threats to production by pests, namely potato late blight (Phytophthora infestans) ... -
Genome-wide association and haplotype-based association mapping of mastitis in lacaune sheep
(Master thesis, 2014-02-17)The aim of this study was to perform a Genome-Wide Association Study (GWAS) and a Haplotype-based Association Mapping to identify potential Quantitative Trail Loci (QTLs) underlying four mastitis-related trails in Lacaune ... -
Genome-wide association mapping of Fusarium head blight resistance in Norwegian spring and winter wheat lines
(Master thesis, 2015-07-16)Fusarium graminearum is a species of fungal pathogens known to cause Fusarium head blight impacting grain quality and yield of Norwegian wheat. The genetic background of this disease have been studied over the past two ... -
Genome-wide association study of resistance to cardiomyopathy syndrome (CMS) in Atlantic salmon (Salmon salar L.)
(Master thesis, 2019)Cardiomyopathy syndrome (CMS) is considered as a serious viral disease in Norwegian farmed Atlantic salmon. Outbreaks of the disease occur without any observable signs and CMS primarily affects adult salmon. In 2011, piscine ... -
Genome-wide association study of the genetic basis for resistance to IPNV in rainbow trout
(Master thesis, 2022)Infectious Pancreatic Necrosis (IPN), caused by the IPN virus, is one of the major threats to the Norwegian rainbow trout (NRT) industry. Despite disinfection, effective management, traditional breeding programs, and efforts ... -
Genomic architecture and complex traits in norwegian red cattle
(PhD Thesis;2010:50, Doctoral thesis, 2010)The predominant cattle breed in Norway, Norwegian Red cattle (NRF), is an admixed breed formed from local Norwegian breeds and imported animals from other Nordic breeds. The extensive phenotypic records for NRF represent ... -
Genomic methods in breeding programs: Parental assignment, triploid genomics and case-parental control modelling
(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
(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 ... -
Genomic predictions including known QTL for reproduction traits in swine
(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 responses of salmonids to pathogenic agents and nutritional interventions
(PhD Thesis;2009:43, Doctoral thesis, 2009)Aquaculture exposes salmonid fish to diverse stressors, including pathogens and inadequate nutrition. The identification of molecular basis underlying compromised health and growth caused by these factors is confounded by ... -
Genomic structural variations as drivers of adaptation in salmonid fishes
(PhD Thesis;2023:26, Doctoral thesis, 2023)Structural variations (SVs), e.g. deletions, insertions, inversions and duplications of sequences, are a major source of genomic variation affecting more base pairs in the genome than single nucleotide polymorphisms (SNPs). ... -
Genomics exploring population structure and sex determination in Atlantic cod (Gadus morhua)
(PhD Thesis;2019:102, Doctoral thesis, 2019)Atlantic cod (Gadus morhua) is a benthopelagic cold-water marine species found across the North Atlantic Ocean. Thanks to its historical and current significance as an important food resource it is one of the most well-known ... -
Genomics of bovine milk fat composition
(PhD Thesis;2018:19, Doctoral thesis, 2018)Bovine milk is a highly regarded food source. Still, some milk fatty acids may have unfavourable health effects and can influence manufacturing properties of dairy products. Individual milk fatty acids show moderate ... -
