A high density linkage map enables a second generation collared flycatcher genome assembly and reveals the pattern of avian recombination rate variation and chromosomal evolution.
kawakami, takeshi; smeds, Linnea; Backström, Niclas; Husby, Arild; Qvarnström, Anna; Ellegren, Hans; Olason, Pall; Mugal, Carina (Journal article; Peer reviewed, 2014-06-17)Detailed linkage and recombination rate maps are necessary to use the full potential of genome sequencing and population genomic analyses. We used a custom collared flycatcher 50 K SNP array to develop a high-density linkage ... -
DNA-basert overvåking av den skandinaviske jervbestanden 2008-2011
Flagstad, Øystein; Tovmo, Mari; Balstad, Torveig; Johansson, Malin; Syslak, Line; Eriksen, Line Birkeland; Spets, Merethe Hagen; Søgaard, Caroline Danielsen; Ellegren, Hans; Brøseth, Henrik (NINI rapport;843, Research report, 2012)Genetiske analyser er de siste årene blitt implementert som et viktig verktøy i rovviltovervåkingen i Skandinavia. I særlig grad har antallet DNA-analyser av ekskrementer økt betydelig. Det siste tiåret er det gjennomført ... -
Estimation of linkage disequilibrium and interspecific gene flow in Ficedula flycatchers by a newly developed 50k SNP array.
Kawakami, Takeshi; Backström, Niclas; Burri, Reto; Husby, Arild; Olason, PI; Rice, A M; Qvarström, Anna; Ellegren, Hans (Journal article; Peer reviewed, 2014)With the access to draft genome sequence assemblies and whole-genome resequencing data from population samples, molecular ecology studies will be able to take truly genome-wide approaches. This now applies to an avian model ... -
Genomic identification and characterization of the pseudoautosomal region in highly differentiated avian sex chromosomes
Burri, Reto; Bolivar, Paulina; Husby, Arild; Qvarnström, Anna; Uebbing, Severin; Ellegren, Hans; Smeds, Linnea; Kawakami, Takeshi (Journal article; Peer reviewed, 2014)The molecular characteristics of the pseudoautosomal region (PAR) of sex chromosomes remain elusive. Despite significant genome-sequencing efforts, the PAR of highly differentiated avian sex chromosomes remains to be ... -
Increasing the power of genome wide association studies in natural populations using repeated measures - evaluation and implementation
Rönnegård, Lars; McFarlane, S. Eryn; Husby, Arild; Kawakami, Takeshi; Ellegren, Hans; Qvarnström, Anna; Freckleton, Robert (Journal article; Peer reviewed, 2016)1. Genomewide association studies (GWAS) enable detailed dissections of the genetic basis for organisms’ ability to adapt to a changing environment. In long-term studies of natural populations, individuals are often marked ... -
Insights into the genetic architecture of morphological and sexually selected traits in two passerine bird species
Silva, Catarina; McFarlane, S. Eryn; Hagen, Ingerid Julie; Rönnegård, Lars; Billing, Anna; Kvalnes, Thomas; Kemppainen, Petri; Rønning, Bernt; Ringsby, Thor Harald; Sæther, Bernt-Erik; Qvarnström, Anna; Ellegren, Hans; Jensen, Henrik; Husby, Arild (Journal article; Peer reviewed, 2017)Knowledge about the underlying genetic architecture of phenotypic traits is needed to understand and predict their evolutionary dynamics. The number of causal loci underlying most phenotypic traits, the magnitude of their ... -
Whole-genome resequencing of extreme phenotypes in collared flycatchers highlights the difficulty of detecting quantitative trait loci in natural populations
Kardos, Marty; Husby, Arild; McFarlane, S. Eryn; Qvarnström, Anna; Ellegren, Hans (Journal article, 2016)Dissecting the genetic basis of phenotypic variation in natural populations is a long-standing goal in evolutionary biology. One open question is whether quantitative traits are determined only by large numbers of genes ...
