  2. 1. Pawsitive selection : Genetics of dog-human communication

    Author : Mia Persson; Per Jensen; Lina Roth; Dominic Wright; Ádám Miklósi; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Through domestication and recent selection, dogs have evolved a unique set of communicative skills to attract and redirect human attention. These social skills have not been seen to the same extent in socialised wolves and are therefore believed to have a significant genetic basis. READ MORE

  4. 2. Disentangling small genetic differences in large Atlantic herring populations: comparing genetic markers and statistical power

    Author : Lena C. Larsson; Linda Laikre; Nils Ryman; Lorenz Hauser; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conservation genetics; marine fish; spatial and temporal genetic variation; molecular marker comparison; allozyme; microsatellite; selection; fisheries management; Biology; Biologi; populationsgenetik; Population Genetics;

    Abstract : Genes are the foundation of evolution and biodiversity. The genetic structure of natural populations needs to be understood to maintain exploited resources rationally. This thesis focuses on genetic variability and methods to determine spatial and temporal genetic heterogeneities. READ MORE

  5. 3. Multiplex markers in a plant breeding perspective

    Author : Mats Hansen; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant biochemistry; plant breeding; SNP; RAPD; molecular markers; AFLP; Växtbiokemi;

    Abstract : Plant breeding is largely depending on the repeated selection for desirable traits. This process is both time and labour consuming, making the development of commercial plant varieties a slow and costly activity. READ MORE

  6. 4. Avian MHC: variation and selection in the wild

    Author : Helena Westerdahl; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymorphism; balancing selection; cDNA; avian malaria; great reed warbler; Djurekologi; bird; Animal ecology; immune defence; MHC class II; Major Histocompatibility Complex; MHC class I;

    Abstract : In vertebrates the Major Histocompatibility Complex (MHC) plays a central role in the specific immune defence against various pathogens. Compared with other coding genes the MHC genes exhibit an extremely high level of polymorphism that is maintained by balancing selection. READ MORE

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

    Author : Christer Halldén; Malmö Klinisk kemi; []
    Keywords : 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;

    Abstract : 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. READ MORE
