2. 1. Gene transfer by interspecific hybridization in bryophytes

   Author : Weerachon Sawangproh; Biodiversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; homozygote; heterozygote; admixture; single nucleotide polymorphism; STRUCTURE; PCoA; hybrid index; inbreeding; outbreeding; hybrid depression; heterosis; phylogeny; purging selection; genetic purging; genotype; phenotype; sympatry; allopatry;

   Abstract : The role of hybridization in evolution has been debated for more than a century regarding bryophytes (mosses, liverworts, and hornworts) as well as most other organisms. Bryophytes have haplodiplontic life cycles with a dominant haploid generation. READ MORE

4. 2. Underlying genetic mechanisms of hereditary dystrophies in retina and cornea

   Author : Jonsson Frida; Irina Golovleva; Carlo Rivolta; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cornea; retina; gene; mutation detection; inherited diseases; genetik; Genetics;

   Abstract : Inherited retinal and corneal dystrophies represent a group of disorders with great genetic heterogeneity. Over 250 genes are associated with retinal diseases and 16 genes are causative of corneal dystrophies. READ MORE

5. 3. Genetic Variation in Mhc Class II B in Atlantic Salmon: Evolutionary and Ecological Perspectives

   Author : Åsa Langefors; Biodiversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; recombination; genetic variation; Mhc class II B; Atlantic salmon; evolution; population genetics; Animal ecology; Djurekologi;

   Abstract : The Major Histocompatibility Complex (Mhc) genes are crucial for the recognition of self and non-self peptides by the immune defence system. They are extremely variable in most studied vertebrate species. I have studied the extent and the importance of Mhc variation in Atlantic salmon (Salmo salar), mainly from the Baltic Sea. READ MORE

6. 4. Using Minisequencing Technology for Analysing Genetic Variation in DNA and RNA

   Author : Mona Fredriksson; Ann-Christine Syvänen; Aarno Palotie; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular medicine; microarray; minisequencing; molecular medicine; single nucleotide polymorphism; stem cell transplantation; whole genome amplification; allelic imbalance; alternative splicing; Molekylärmedicin; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ;

   Abstract : In this thesis, the four-color fluorescence tag-microarray minisequencing system pioneered by our group was further developed and applied for analysing genetic variation in human DNA and RNA. A SNP marker panel representing different chromosomal regions was established and used for identification of informative SNP markers for monitoring chimerism after stem cell transplantation (SCT).

7. 5. Detecting Deletions by Analysis of Genetic Markers in Pedigrees

   Author : Anna Johansson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytogenetics; Genetik; Genetics; Biologi; genetic marker; pedigree; Protein S deficiency; Biology; PROS1; deletion; null allele; cytogenetik;

   Abstract : A deletion is defined as a missing piece of a chromosome, ranging in size from as small as a single base pair to as much as an entire arm of a chromosome. Deletions can cause diseases, but may also have a neutral effect in the genome. READ MORE
