Spring 2019
A reproductive phenotype that has high variability, repeatability, heritability, and association with fertility could become an excellent candidate for genetic selection to augment fertility in dairy cows. Therefore, the general objective of this research was to evaluate the aforementioned...

Genomic selection for pork quality and carcass traits in both cross- and pure-bred populations
DownloadSpring 2015
Pork quality and carcass characteristics are now being integrated into swine breeding objectives because of their economic value. Understanding the genetic basis for these traits is necessary for this to be accomplished. The main objective of this study was to improve pork quality traits in two...

Breast cancer is the most common cancer among women in the developed world. The disease results from the combined effects of genetic, environmental, reproductive and lifestyle risk factors. Germline DNA variations identified thus far by linkage and genome-wide association studies (GWASs) account...

Improving Accuracy of Genomic Prediction for Economically Important Traits in Canadian Holstein Dairy Cattle
DownloadSpring 2017
Milk is a valuable source of energy, high quality protein, and several key minerals and vitamins for humans. Selection for milk production in dairy cattle was first based on phenotype and pedigree information and the knowledge of genetic parameters for the trait of interest. However, substantial...

Investigating the genetic basis of boldness and reproductive performance traits in the grey seal (Halichoerus grypus)
DownloadSpring 2022
Individual variation provides the material for natural selection to act upon, influencing ecological and evolutionary processes. Much phenotypic variation in traits, such as behaviour and life-history, have a moderate to high heritable component, suggesting that these traits may have adaptive...

Looking beyond the standard genome-wide association study: Biologically-motivated methodological approaches to discover novel genetic variants associated with complex human traits and disease
DownloadFall 2018
The standard approach for testing associations between common single nucleotide genetic variants (referred to as single nucleotide polymorphisms or SNPs) and disease entails testing disease associations for each SNP in the genome individually. This “hypothesis-free” approach has identified...

Polar bears (Ursus maritimus) were among the first large mammals to be assessed for genetic variation in the wild, and they remain a common subject of genetics studies. Although recent advances in genotyping technology have allowed for more accurate determination of population structure and the...

Relationship between trained sensory and objective measured meat quality attributes in crossbred Canadian beef cattle after 3- and 29-days post-mortem aging
DownloadSpring 2022
Meat quality attributes are pivotal for the beef industry. Studies across Canada showed major beef quality concerns originate from inconsistency of palatability attributes. To improve these traits genetically, they should be standardly measured, their (co)variance components and genetic...

Trade-offs between wood density and radial growth in the Region H white spruce Controlled Parentage Program, Alberta, Canada
DownloadFall 2019
Trade-offs between wood density and radial growth rate in white spruce were investigated. Decreases in wood density associated with increased radial growth rate have been well documented in several tree species, including white spruce (Picea glauca (Moench) Voss)....
