  1. 1. Catching the Spore killers : Genomic conflict and genome evolution in Neurospora

    Författare :Jesper Svedberg; Hanna Johannesson; Mark A. Kirkpatrick; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Genomics; genomic conflict; genome evolution; meiotic drive; spore killer; suppression of recombination; inversions; fungi; Neurospora; Biologi; Biology;

    Sammanfattning : A genome is shaped by many different forces. Recombination can for instance both create and maintain genetic diversity, but the need to locally reduce recombination rates will also leave specific signatures. LÄS MER

  3. 2. Genomic and transcriptomic investigation of reproductive incompatibility in Drosophila

    Författare :Guilherme Costa Baião; Lisa Klasson; Alistair Darby; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wolbachia; Drosophila; Drosophila paulistorum; Differential Gene Expression; Reproductive Incompatibility; Reproductive Isolation; Comparative Genomics; Transcriptomics; RNA-Seq; Heteroplasmy; Mitochondria; Genomic conflict; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : Both nuclear and cytoplasmic elements can contribute to the emergence of reproductive incompatibilities that influence evolution and speciation. In the projects that compose this thesis, we use genomics and transcriptomics to study some of those elements in Drosophila. LÄS MER

  4. 3. Determinants of genomic diversity in the collared flycatcher (Ficedula albicollis)

    Författare :Ludovic Dutoit; Hans Ellegren; Asher Cutter; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; collared flycatcher; Ficedula albicollis; enetic diversity; sexual conflict; effective population size; nucleotide diversity; linked selection; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Individuals vary from each other in their genetic content. Genetic diversity is at the core of the evolutionary theory. Rooted in a solid theoretical framework developed as early as the 1930s, current empirical observations of genomic diversity became possible due to technological advances. LÄS MER

  5. 4. Genomic studies of sex differences : On mutations, recombination, and sexual antagonism in songbirds

    Författare :Hongkai Zhang; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sex differences; mutation; recombination; sexual conflict; sexual antagonism; sexually antagonistic selection; Great reed warbler; Acrocephalus arundinaceus;

    Sammanfattning : Many organisms have separate sexes, i.e., males and females. The presence of separate sexes causes sex-specific selection regimes and sexual antagonism, which can lead to sex differences in morphology, physiology, and behaviours. LÄS MER

  7. 5. The genomic basis of the response to female-limited X-chromosome evolution

    Författare :Yesbol Manat; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; X chromosome; Sex chromosome; Drosophila melanogaster; Experimental evolution; sexual selection; intralocus sexual conflict;

    Sammanfattning : In this thesis, I attempted to achieve a better understanding of the nature of X-linked polymorphic loci using a female-limited X chromosome (FLX) experimental evolution in Drosophila melanogaster. I expected that expressing the evolved X chromosome will result in an increase in female fitness and a decrease in male fitness. LÄS MER
