  2. 1. The balance between sex and asex: evolutionary genetic studies of reproductive variation in Allium vineale

    Author : Alf Ceplitis; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ontogeny; growth animal ; Allium vineale; Development biology; evolution; sexual reproduction; reproductive systems; embryology; Utvecklingsbiologi; ontogeni; embryologi; Genetics; cytogenetics; Genetik; cytogenetik;

    Abstract : Evolutionary theory predicts a disadvantage to sexual reproduction. This manifests itself either by the higher growth rate of asexual females in a dioecious species, or by the higher transmission rate of a gene conferring asexual female function to its carriers in a hermaphrodite species.

  4. 2. Investigation of Mechanics of Mutation and Selection by Comparative Sequencing

    Author : Michael C. Zody; Kerstin Lindblad-Toh; Leif Andersson; Chad Nusbaum; Henrik Kaessmann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chicken; chimpanzee; human; evolution; segmental duplication; structural variation; chromosomal rearrangement; comparative genomics; positive selection; selective sweep; Genetics; Genetik; Genetics; genetik;

    Abstract : The process of evolution is of both scientific and medical interest. This thesis presents several studies using complete genomic reference sequences, comparative genomic data, and intraspecific diversity data to study the two key processes of evolution: mutation and selection.

  5. 3. The Complex Genetics of Mouse Reproduction and Arhritis

    Author : Maria Liljander; Immunologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; morula; B10.Q mice; genetics.; Pregnancy; CIA; reproduction; QTL; superovulation; blastocysts; oocytes; litter size; RA; NFR N mice; MHC;

    Abstract : ABSTRACT Optimal breeding of mice is very important in biomedical science today. The understanding why some strains breed better and some worse enable scientists to create better in vivo models for human diseases. READ MORE

  6. 4. Molecular ecology of marine mammals

    Author : Morten Tange Olsen; Per Palsbøll; Martine Bérubé; William “Bill” Amos; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Marine mammals; molecular ecology; life history; environmental change; phenotypic plasticity; SNPs; telomeres; molekylärgenetik; Molecular Genetics;

    Abstract : Marine mammals comprise a paraphyletic group of species whose current abundance and distribution has been greatly shaped by past environmental changes and anthropogenic impacts. This thesis describes molecular ecological approaches to answer questions regarding habitat requirements, genetic differentiation, and life-history trade-offs in three species of marine mammals.

  7. 5. Exploring genetic diversity in natural and domestic populations through next generation sequencing

    Author : Nima Rafati; Leif Andersson; Carl-Johan Rubin; Alvaro Martinez Bario; Craig Primmer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecological adaptation; seasonal reproduction; Atlantic herring; domestication; speciation; rabbit; skeletal atavism; Shetland ponies; NGS; SMRT sequencing; genome; transcriptome; assembly; structural variation; genetic diversity; HCE; TSHR; SHOX; CRLF2;

    Abstract : Studying genetic diversity in natural and domestic populations is of major importance in evolutionary biology. The recent advent of next generation sequencing (NGS) technologies has dramatically changed the scope of these studies, enabling researchers to study genetic diversity in a whole-genome context.
