2. 1. Evolutionary genomics in Corvids : – From single nucleotides to structural variants

   Author : Matthias H. Weissensteiner; Jochen B.W. Wolf; Manfred Grabherr; Kateryna M. Makova; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; evolutionary genetics; genomics; population genetics; selection; recombination; chromosomal features; colouration; insertion; deletion; inversion; crow; tandem repeat; transposable element; gene expression;

   Abstract : Heritable genetic variation is the raw material of evolution and can occur in many different forms, from altering single nucleotides to rearranging stretches of millions at once. DNA mutations that result in phenotypic differences are the basis upon which natural selection can act, leading to a shift of the frequency of those mutations. READ MORE

4. 2. Genome Evolution of Neurospora tetrasperma

   Author : Yu Sun; Hanna Johannesson; Siv Andersson; Toni Gabaldon; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Neurospora tetrasperma; next-generation sequencing; introgression; intron; chromosomal inversion; codon usage; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Abstract : In this thesis work, I have used a comparative genomics approach to study a fungal model organism, Neurospora tetrasperma. My specific focus has been on genomic introgression, intron evolution, chromosomal structural rearrangements and codon usage. READ MORE

5. 3. Structural chromosomal aberrations and neuropsychiatric disorders

   Author : Tonnie Johannesson; Göteborgs universitet; []
   Keywords : Autism spectrum disorders; chromosomes; FISH; balanced; translocations;

   Abstract : Infantile autism (IA) is a severe neurodevelopment disorder with a complex genetic predisposition. The underlying causes of autism are still not understood. READ MORE

6. 4. The evolution of flat periwinkles Littorina fabalis and L. obtusata emhasizing mitochondrial introgression and restricted recombination

   Author : Petri Kemppainen; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Speciation; Local adaptations; Ecotypes; Mitochondrial DNA; Introgression; Restricted recombination; Positive selection; Inversions; Chromosomal rearrangements;

   Abstract : The evolution of species takes in general very long time and different mechanisms are likely to operate during the various stages of this process. Accordingly speciation should be studied at different levels of species divergence. READ MORE

7. 5. Investigation of Mechanics of Mutation and Selection by Comparative Sequencing

   Author : Michael C. Zody; Kerstin Lindblad-Toh; Leif Andersson; Chad Nusbaum; Henrik Kaessmann; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; chicken; chimpanzee; human; evolution; segmental duplication; structural variation; chromosomal rearrangement; comparative genomics; positive selection; selective sweep; Genetics; Genetik; Genetics; genetik;

   Abstract : 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.
