  1. 16. Genome Evolution of Neurospora tetrasperma

    Författare :Yu Sun; Hanna Johannesson; Siv Andersson; Toni Gabaldon; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 17. Sexual Conflict and Gene Expression in Drosophila melanogaster

    Författare :Paolo Innocenti; Edward Morrow; Göran Arnqvist; Andrew G Clark; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sexual conflict; sexual selection; male-female coevolution; gene expression; transcriptome; microarrays; sexual dimorphism; Drosophila; Biology; Biologi; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Sexual conflict is broadly defined as a conflict between the evolutionary interests of the two sexes. Depending on the genetic architecture of the traits involved, it can occur at the level of male-female interactions or take the form of selection acting to change the mean of a shared trait against the sign of its genetic correlation.

  4. 18. Translational research of the quaking gene : Focusing on the conjunction between development and disease

    Författare :Bryn Farnsworth; Lina Emilsson; Roman Chrast; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; QKI; glia; oligodendrocyte; Alzheimer s; schizophrenia; zebrafish; statistics; morpholino; Biologi med inriktning mot evolutionär organismbiologi; Biology with specialization in Evolutionary Organismal Biology;

    Sammanfattning : Quaking (QKI) is an RNA binding protein involved in the post-transcriptional regulation of gene expression. Originally identified as the cause of hypomyelination in a mouse mutant, it has since been consistently implicated in a wide range of neurological diseases. LÄS MER

  5. 19. Population genetic history and patterns of admixture : Examples from northeastern and southern Africa

    Författare :Nina Hollfelder; Mattias Jakobsson; Michele Ramsay; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; population structure; genetic admixture; genomic variation; Africa; population genomics; lactase persistence; sex-biased admixture; human evolutionary genetics; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi;

    Sammanfattning : The origin of humans lies in Africa, as has been shown by archaeology, paleontology and genetics. Here, we can find the largest genetic diversity and the deepest split among human populations. African genetic diversity has been shaped by a long and complex history. LÄS MER

  7. 20. Population Genetics and Genome Organization of Norway Spruce

    Författare :Hanna Larsson; Martin Lascoux; Bruno Fady; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Picea abies; demographic history; linkage disequilibrium; HMPR; Biologi med inriktning mot evolutionär funktionsgenomik; Biology with specialization in Evolutionary Functional Genomics;

    Sammanfattning : Understanding the underlying genetic causes of adaptation to local conditions is one of the main goals of population genetics. A strong latitudinal cline in the phenotypic trait of bud set is observed in present day populations of Norway spruce (Picea abies (L.) Karst). LÄS MER
