16. The k-assignment polytope, phylogenetic trees, and permutation patterns
Sammanfattning : In this thesis three combinatorial problems are studied in four papers.In Paper 1 we study the structure of the k-assignment polytope, whose vertices are the mxn (0,1)-matrices with exactly k 1:s and at most one 1 in each row and each column. LÄS MER
17. Inferring Ancestry : Mitochondrial Origins and Other Deep Branches in the Eukaryote Tree of Life
Sammanfattning : There are ~12 supergroups of complex-celled organisms (eukaryotes), but relationships among them (including the root) remain elusive. For Paper I, I developed a dataset of 37 eukaryotic proteins of bacterial origin (euBac), representing the conservative protein core of the proto-mitochondrion. LÄS MER
18. Molecular Phylogenetics of Mammals
Sammanfattning : In this thesis, the phylogenetic relationships of the Mammalia have been studied at various levels. Different sources of genetic information have been evaluated and used as phylogenetic markers. These include the well-known mitochondrial genome, cDNA from housekeeping genes and expressed sequence tags from nuclear genes. LÄS MER
19. Marsupial Mitogenomics
Sammanfattning : The relationships of the mammalian infraclass Marsupialia have been investigated by phylogenetic analysis using completely sequenced mitochondrial genomes. The organisation and structure of the marsupial mitochondrial genomes deviates from the general mammalian structure. LÄS MER
20. A forest dark : an evolutionary history of Norway spruce
Sammanfattning : Embedded within the relationships among species is a dense forest of gene trees, each with a potentially unique and discordant history. Such widespread genealogical heterogeneity is expected, but embracing this hierarchy of discordance while reconstructing the histories of populations and species remains a major challenge. LÄS MER
