6. Neurospora tetrasperma from Natural Populations : Toward the Population Genomics of a Model Fungus
Abstract : The study of DNA sequence variation is a powerful approach to study genome evolution, and to reconstruct evolutionary histories of species. In this thesis, I have studied genetic variation in the fungus Neurospora tetrasperma and other closely related Neurospora species. I have focused on N. READ MORE

7. Reconstructing the Human Past using Ancient and Modern Genomes
Abstract : The study of DNA variation is one of the most promising avenues for learning about the evolutionary and historical past of humans and other species. However, the difficulty associated with obtaining DNA directly from ancient remains have for long kept genomic studies of population history trapped in time; confined to interpreting patterns of modern-day variation without direct historical observations.

8. Population Genetics of Human Genomic Elements
Abstract : The genomes of living organisms are composed of a multitude of functional units, which interact with each other and their environment in a highly regulated fashion, to facilitate the expression of an enduring (and evolving) phenotype. Several approaches have emerged in the effort to identify these functional units and explore their activities. READ MORE

9. Chicken domestication : Effects of tameness on brain gene expression and DNA methylation
Abstract : Domestication greatly increases phenotypic variation in a short time span, with selection for a single phenotype and a plethora of associated phenotypic changes as an outcome of the process. The domestication process influences the underlying genomic architecture of a species, and the success and speed of the process is likely influenced by it. READ MORE

10. From the migrations of herders and farmers to the colonial era and the modern-day : Genetic inferences on African demographic history
Abstract : Africa is the birthplace of the human species and home to great linguistic, cultural, and genetic diversity. Despite this, the genetics of the peoples of the continent remains understudied. In this thesis, I apply population genetic approaches, to contribute to the knowledge of human demographic history in Africa. READ MORE
