  1. 1. Fine-scale recombination landscape in the wood white butterfly Leptidea sinapis

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Aleix Palahí i Torres; [2021]
    Nyckelord :recombination; butterfly; Leptidea; population;

    Sammanfattning : Recombination is a genetic process of extreme importance in evolutionary biology. It creates novel haplotypes and breaks down existing ones, and can affect the levels of genetic diversity and the efficacy of selection. It also plays an important role in the evolution of sex chromosomes and the divergence process leading to speciation. LÄS MER

  3. 2. Beyond high mutation highrecombination limit in statisticalgenetics

    Master-uppsats, KTH/Fysik

    Författare :Luc Zorrilla; [2021]
    Nyckelord :Statistical Genetics; Population genetics; Statistical physics; Linkage Equilibrium;

    Sammanfattning : One considers the bi-allelic model in population genetics which describes a population of genomes evolving under the processes of selection, mutation, recombination and drift. A focus is made on the Quasi-Linkage Equilibrium (QLE) phase with recent derivations from Neher and Shraiman, which exists for fast recombinations compared to selection strength and whose dynamics is greatly simplified compared to the general case.

  4. 3. Silicon surface passivation via ultra-thin SiO2, TiO2, and Al2O3 layers

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Anton Ek; [2019]
    Nyckelord :surface passivation; ALD; silicon; solar cell; SiO2; Al2O3; TiO2; stacks; characterization; optimization; RSM; temperature;

    Sammanfattning : Energy traps at the silicon surface originating from discontinuities in the lattice is detrimental to the performance of solar cells. Acting as recombination centers, they offer a location where the charge carriers may easily return to their original energy band after excitation. LÄS MER

  5. 4. Characterization of the Recombination Landscape in Red-Breasted and Taiga Flycatchers

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Evolutionsbiologi

    Författare :Bella Vilhelmsson Sinclair; [2019]
    Nyckelord :recombination; Ficedula parva; Ficedula albicilla; flycatcher; statistical phasing; speciation;

    Sammanfattning : Between closely related species there are genomic regions with a higher level of differentiation compared to the rest of the genome. For a time it was believed that these regions harbored loci important for speciation but it has now been shown that these patterns can arise from other mechanisms, like recombination. LÄS MER

  7. 5. CpG islands, but not their methylation level, are key in the regulation of meiotic recombination in chicken (Gallus gallus)

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Ivar Westerberg; [2019]
    Nyckelord :;

    Sammanfattning : Meiotic recombination plays a fundamental role in many sexually reproducing species. Recombination shuffles the genetic material during the first meiotic cell division resulting in new combinations of alleles within each chromosome. LÄS MER
