  1. 1. Neanderthal genome sequencing : A genetic research study

    Kandidat-uppsats, Uppsala universitet/Institutionen för arkeologi och antik historia

    Författare :Susanna Uhr; [2023]
    Nyckelord :aDNA; genome sequencing; method progression; Neanderthals; modern humans; genetic divergence; interbreeding; aDNA; genom sekvensering; metodutveckling; Neandertalare; moderna människor; genetisk splittring; korsning;

    Sammanfattning : The aim of this study is to provide information regarding the development of aDNA research. The essay also strives to distinguish eventual impact on previous and contemporary conceptions concerning Neanderthal and modern human genetic divergence and possible interbreeding between the two species.

  3. 2. Swedish red clover-associated Rhizobium leguminosarum bv. trifolii share high genetic similarity in the 16S gene but divergence in nod genes

    Master-uppsats, SLU/Department of Plant Biology (from 140101)

    Författare :Tua Lilja; [2023]
    Nyckelord :genetics; nitrogen fixation; sustainability; symbiosis; taxonomy;

    Sammanfattning : Rhizobium leguminosarum biovar trifolii (Rlt) is a root-associated soil bacterium (rhizobia) capable of entering a symbiotic relationship with various species of clover (Trifolium sp.) and fix nitrogen within root nodules. LÄS MER

  4. 3. Optimised PCR protocol for ten microsatellite primers (SSRs) in Fragaria vesca : Facilitating future work analysing genetic diversity and developing efficient conservation strategies

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Lisa Haglund; [2022]
    Nyckelord :Crop wild relatives CWR ; PCR; Microsatellites; Fragaria vesca; Conservation; Genetic diversity;

    Sammanfattning : The world faces severe challenges in providing food security for a growing world population during climate change. This puts pressure on modern agriculture, including adapting crops to new environments and cultivation on less acreage. The tools for adapting crops exist within a species' genetic diversity.

  5. 4. Echo of the Ancients: Evolution of Song in the Avian Family Cettiidae

    Master-uppsats, Uppsala universitet/Paleobiologi

    Författare :Jared Goodstadt; [2022]
    Nyckelord :Cettiidae; song; acoustic analysis; PCA; Mahalanobis distance; phylogeny;

    Sammanfattning : The Cettiidae, a family of primarily small, insectivorous, Asiatic and Austronesian, mountain birds have been the subject of acoustic analysis in the past. However, until this point, an in-depth review of the songs of the entire family had yet to be undertaken. LÄS MER

  7. 5. Development of a DNA barcode for species identification of tuna

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Clara Nordquist; Jonathan Edwall; Leonora Eriksson; Nelly Mäkinen; Minna Sayehban; Matilda Styfberg; [2022]
    Nyckelord :Thunnini; D-loop; mitochondrial control region; CR; 16S; ATP8; COII; Cox2; CytB; COI; Cox1; ND2; NADH dehydrogenase 2;

    Sammanfattning : Today, DNA-barcoding with the gene COI is regularly used in the identification of fish. However, this is not an adequate way of identifying species of tuna due to COI lacking sufficient interspecies divergence. This is problematic since fraud and mislabeling are a major concern within the fish and tuna industries. LÄS MER
