1. Past demography and local adaptation in forest trees : Insights from natural populations and breeding programs of Norway spruce
Sammanfattning : Spatial changes in natural selection patterns can give rise to local adaptation and genetic differentiation between populations. Local adaptation for phenological traits is pronounced in many forest tree species. LÄS MER
2. Candidate gene effects on beef quality
Sammanfattning : The contribution of five candidate genes to the variation in meat tenderness, pH, colour, marbling and water holding capacity (WHC) was analysed in muscle samples from 243 young bulls of Angus, Charolais, Hereford, Limousin, or Simmental breed, raised in Swedish commercial herds. The animals were genotyped for single nucleotide polymorphisms (SNPs) in the genes encoding calpain 1 (CAPN1:c. LÄS MER
3. Breeding for sustainable milk production : from nucleus herds to genomic data
Sammanfattning : The overall aim of the research reported in this thesis was to investigate ways to mitigate deterioration in functional traits and reduce the environmental impact of milk production. The more specific objectives were to obtain new information about the selection of bull dams for functional traits in an open nucleus herd, to monitor ongoing genetic trends in functional traits, and to examine a breeding program with genomic selection and contractor herds that records specific indicator traits correlated with environmental impact.

4. Avian migration: the role of geomagnetic cues
Sammanfattning : The regularity and scale of bird migrations has impressed mankind for generations. Birds rely on an inherited migratory program to guide them during the journey; however, recent evidence suggests that additional external cues are necessary. LÄS MER
5. Milk Genomics – Impact of Genetic Polymorphism on Bovine Milk Composition and Processability
Sammanfattning : Milk genomics is a new area of research that explores the relations between cow genetics and milk characteristics. Identifying the genes controlling compositional and technological traits of milk will give opportunities to select cows for targeted milk production. In this thesis, the impact of different genetic approaches, i.e. LÄS MER
