1. Seminal Influence on the Oviduct : Mating and/or semen components induce gene expression changes in the pre-ovulatory functional sperm reservoir in poultry and pigs
Sammanfattning : Internal fertilization occurs in birds and eutherian mammals. Foetal development, however, is either extra- respectively intra-corpore (egg vs uterus). LÄS MER
Sammanfattning : The aim throughout this thesis has been to investigate the underlying genetics of behaviours and feather colour and plumage patterns by using chickens as a model organism. Chickens are extremely important as a food source, both in terms of egg, as well as meat production. LÄS MER
Sammanfattning : In quantitative genetics the relationship between genetic and phenotypic variation is investigated. The identification of these variants can bring improvements to selective breeding, allow for transgenic techniques to be applied in agricultural settings and assess the risk of polygenic diseases. LÄS MER
Sammanfattning : Ageing is defined as the deterioration of an individual's physiological performance with advancing age, which leads to a decrease in reproduction and/or survival. The question why most organisms age has preoccupied humans for millennia and, over the last decades, resulted in an ever-increasing research effort to understand this phenomenon. LÄS MER
Sammanfattning : Domestication can serve as a study system of rapid evolutionary change with wide-ranging effects on traits in animals. The chicken was domesticated from the Red Junglefowl and has diverged in behaviour, morphology and life history traits. LÄS MER
