  1. 6. Characterization and Use of a Multiplex PCR-based System: Random amplified Polymorphic DNA

    Författare :Christer Halldén; Malmö Klinisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DNA mixtures; competition; graphical genotypes; bulked segregant analysis; linkage map; genetic distance; RFLP markers; RAPD markers; oilseed rape; sugar beet; Genetics; cytogenetics; Genetik; cytogenetik;

    Sammanfattning : Random amplified polymorhic DNA (RAPD) is a PCR-based marker system that makes use of universal sets of short oligonucleotides that amplify random DNA fragments under low-stringency conditions. The RAPD marker system has found widespread use and possesses a number of very positive features, being a multiplex and universal system. LÄS MER

  3. 7. Genome Variation in Human Populations : Exploring the Effects of Demographic History and the Potential for Mapping of Complex Traits

    Författare :Åsa Johansson; Ulf Gyllensten; Marta Alarcon; Andrew Clark; Uppsala universitet; []
    Nyckelord :Genetics; genetics; evolution; microsatellie; SNP; selection; linkage disequilibrium; haplotype; Genetik;

    Sammanfattning : A major challenge in human genetics is to understand the genetic variation underlying common diseases. In this thesis, I focus on forces creating differences between individuals and genomic regions, methods for characterizing genomic variation, and the association between genomic and phenotypic variation.

  4. 8. Extraction and Chromatography of targeted emission markers in atmospheric aerosols

    Författare :Hafiz Abdul Azeem; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atmospheric aerosols; emission markers; mass spectrometry; supercritical CO2; trace analysis;

    Sammanfattning : Atmospheric aerosols are a highly complex and dynamic mixture of solid particles, liquid deplots and gases. They travel across the continents and affect global climate and human health in various ways, often negatively. One important aspect of research in atmospheric aerosols is the investigation of emissions to the atmosphere from various sources. LÄS MER

  5. 9. Quantitative Genetics and Genome Structure in a Wild Population: the Use of a Great Reed Warbler Pedigree

    Författare :Mikael Åkesson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; genome mapping ; AFLP; microsatellite; synteny; heterochiasmy; recombination; chicken; great reed warbler ; bird; Genetics; cytogenetics; Genetik; cytogenetik; Animal ecology; trait correlation ; Djurekologi; animal model ; selection; Djurs anatomi och morfologi; animal morphology; Animal anatomy; heritability;

    Sammanfattning : Long-term studies of birds play an important role in the understanding of quantitative traits in natural populations. The relative ease by which individual birds can be monitored and caught in the wild enable us collect detailed information from individuals throughout their life time, sometimes from several generations in a population.

  7. 10. Evolutionary Studies of the Mammalian Y Chromosome

    Författare :Linda Hellborg; Hans Ellegren; Terry Burke; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Y chromosome; field vole; cattle; selection; primer design; Genetik; Clinical genetics; Klinisk genetik;

    Sammanfattning : Sex chromosomes are useful in elucidating the evolutionary factors affecting diversity and divergence. In particular, Y chromosome analyses may complement studies using mitochondrial DNA for inferring sex-specific population genetic processes. LÄS MER
