Analysis of mentality traits in Rhodesian Ridgebacks
(Master thesis, 2013-10-28)The object of this study was to identify broader traits from mentality test results in a cohort of 2022 Rhodesian Ridgebacks , to estimate heritabilities for the underlying variables and the broader traits and to predict ... -
Discolouration of the dorsal white musculature of farmed Atlantic salmon (Salmo salar L.) in Norway, characterised by histological and transcriptional methods
(Master thesis, 2016)Focal melanisation in the white muscle of farmed Atlantic salmon (Salmo salar L.) has become a common finding in Norway. Depending on the magnitude of such changes, muscle tissue (fillets) are graded to lower quality, ... -
Evaluation of vGWAS, a test for determining scenarios of epistasis
(Master thesis, 2013-07-09)A number of software packages have been developed for the detection of epistatic QTL. Nevertheless, none of these approaches could assure the optimal detection of epistasis. There are a number of limitations in these ... -
Fine mapping of two QTL regions associated with inguinal hernia in pig
(Master thesis, 2015-07-16)Pigs suffering from hernias are of concern for pig producers as they can lead to poor animal welfare and economic loss for the producer. Inguinal and scrotal hernia describes instances where abdominal contents protrude ... -
Gene expression, phylogenetic and syntenic analyses of pantophysin (Pan I) and synaptophysin-like2 (Sypl2) genes in Atlantic cod (Gadus morhua L.)
(Master thesis, 2012-10-18)The pantophysin (Pan I) locus reveals differences between Norwegian coastal cod (NCC) and Northeast Arctic cod (NEAC) populations that are highly significant, temporally stable and larger than for any other genetic marker. ... -
Genetic analysis of sheepdog trials in Norway - a proposal of new trait definitions and improved recording in Border Collie
(Master thesis, 2015-01-27)Abstract The aim of this study was to evaluate the quality of the data material provided from sheepdog trials in Norway, estimate heritabilities and repeatabilities for the traits included in the trial, as well as ... -
Genetic parameters and response to selection for body weight, fillet traits, body size traits and survival in Nile Tilapia (Oreochromis niloticus)
(Master thesis, 2017)This study evaluates the genetic parameters and selection responses in relation to harvest body weight, fillet yield, fillet weight, body size traits (length, depth, thickness) and survival of GenoMar Supreme Tilapia (GST™) ... -
Genetic variation in the haemoglobin of the Atlantic cod(Gadus morhua) in trans-Atlantic populations
(Master thesis, 2012-10-05)It can be concluded that Val55-Ala62 haplotype predominated in the Greenland, Canadian, Iceland, and Lofoten NEA, Østersjøen Inner while Met55-Lys62 was mainly found in Østersjøen outer and Skagerrak/Kattegat. The Canadian ... -
Genotype imputation based on discriminant and cluster analysis
(Master thesis, 2012-11-09)The recent development of high-throughput systems for genotyping SNP in Eukaryote has led to an extraordinary amount of research activity, particularly in areas such as whole-genome selection of livestock and ... -
One moment in time : Gene expression analysis of honey bees; nurse bees v.s. foragers
(Master thesis, 2012-06-14)Honey bees live in complex societies based on a division of labour. The honey bee workers specialise in different tasks throughout their lives, starting off as nurse bees and ending as foragers. The nurse bees and foragers ... -
The accuracy of across population genomic predictionusing a Bayesian variable selection model
(Master thesis, 2015-11-05)Background: The use of information across populations is an attractive approach to increase the accuracy of genomic prediction for numerically small populations. However, accuracies of across population genomic prediction, ...
