  1. 1. Archaeological Genetics - Approaching Human History through DNA Analysis

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Evangelia Daskalaki; Uppsala universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ancient DNA; pyrosequencing; molecular genetics; aDNA; neolithization; evolutionary genetics; mtDNA; viking age; archaeological genetics; genetik; evolutionsgenetik; naturvetenskap; neolitisering; vikingatid; arkeologisk genetik; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : There are a variety of archaeological questions, which are difficult to assess by traditional archaeological methods. Similarly, there are genetic and population genetic questions about human evolution and migration that are difficult to assess by studying modern day genetic variation. READ MORE

  2. 2. Effects of Selection and Demography on DNA Polymorphism in Black Mustard (Brassica nigra)

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Per Sjödin; Uppsala universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; population genetics; Genetik; NATURAL SCIENCES Biology Cell and molecular biology Genetics; NATURVETENSKAP Biologi Cell- och molekylärbiologi Genetik;

    Abstract : The evolution of three genes from the CONSTANS-LIKE gene family is studied in Brassica nigra. We use a combination of population genetic and phylogenetic techniques in order to assess the relative importance of selection and demography on the pattern of DNA variation. READ MORE

  3. 3. Neurospora tetrasperma from Natural Populations Toward the Population Genomics of a Model Fungus

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Pádraic Corcoran; Uppsala universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Neurospora; poulation genetics; genomes; introgression; Evolutionary Genetics; Evolutionär genetik;

    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

  4. 4. Reconstructing the Human Past using Ancient and Modern Genomes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Pontus Skoglund; Uppsala universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; population genetics; paleogenomics; human evolution; Evolutionary Genetics; Evolutionär genetik;

    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.

  5. 5. The balance between sex and asex: evolutionary genetic studies of reproductive variation in Allium vineale

    University dissertation from Department of Genetics, Lund University

    Author : Alf Ceplitis; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ontogeny; growth animal ; Allium vineale; Development biology; evolution; sexual reproduction; reproductive systems; embryology; Utvecklingsbiologi; ontogeni; embryologi; Genetics; cytogenetics; Genetik; cytogenetik;

    Abstract : Evolutionary theory predicts a disadvantage to sexual reproduction. This manifests itself either by the higher growth rate of asexual females in a dioecious species, or by the higher transmission rate of a gene conferring asexual female function to its carriers in a hermaphrodite species.
