1. Mutation and Diversity in Avian Sex Chromosomes
Sammanfattning : Sex chromosomes are useful for the study of how factors such as mutation, selection, recombination and effective population size affect diversity and divergence.A comparison of gametologous introns in seven different bird species revealed a complete lack of diversity on the female-specific W chromosome. LÄS MER
2. Detecting Signatures of Selection within the Dog Genome
Sammanfattning : Deciphering the genetic basis of phenotypic diversity is one of the central aims of biological research. Domestic animals provide a unique opportunity for making substantial progress towards this goal. LÄS MER
3. Chicken Genomics - Linkage and QTL mapping
Sammanfattning : 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. LÄS MER
4. Investigation of Mechanics of Mutation and Selection by Comparative Sequencing
Sammanfattning : The process of evolution is of both scientific and medical interest. This thesis presents several studies using complete genomic reference sequences, comparative genomic data, and intraspecific diversity data to study the two key processes of evolution: mutation and selection. LÄS MER
5. Tracing selection and adaptation along an environmental gradient in Populus tremula
Sammanfattning : The distribution of the expressed genotype is moved around in the population over time byevolution. Natural selection is one of the forces that act on the phenotype to change the patterns ofnucleotide variation underlying those distributions. LÄS MER
