1. Biochemical and genetic markers after subarachnoid haemorrhage
Abstract : ABSTRACT Background: Subarachnoid haemorrhage is a devastating disease with high morbidity and mortality despite novel treatment options are available. There are no established methods to measure the brain damage occurring due to the bleed and its complications and to predict early neurological outcome of the disease. READ MORE

2. Avian Genome Evolution - Gene Expression, Gene Divergence and Sexual Dimorphism
Abstract : This study has focused on: (i) differences in how males and females use the genes in the genome, (ii) how sex chromosomes evolve and (iii) how the evolutionary rate of genes are affected by the chromosome on which they are located on and the gene expression level they experience. A large-scale microarray was developed for the zebra finch, Taeniopygia guttata and techniques were developed so that this microarray could also be used for wild passerine birds. READ MORE

3. Genetics and the Origin of Two Flycatcher Species
Abstract : In this thesis, different genetic tools are used to investigate pre- and postzygotic barriers to gene exchange and their role in speciation in the pied flycatcher (Ficedula hypoleuca) and the collared flycatcher (F. albicollis). This species complex consists of four genetically distinct clades that apparently diverged in allopatry (I). READ MORE

4. Chicken Genomics - Linkage and QTL mapping
Abstract : This thesis presents results from genetic studies conducted in the chicken (Gallus gallus). The domestication of chicken is believed to have been initiated approximately 7,000 – 9,000 years ago in Southeast Asia. READ MORE

5. The Evolution of Sex Chromosomes and Dosage Compensation in Structurally Dynamic Butterfly Genomes
Abstract : Dimorphic sex chromosomes have evolved independently throughout evolution from initially homologous autosomes. Recombination suppression between the sex chromosomes causes one sex chromosome to degenerate, which will influence evolution of sex-linked genes. READ MORE
