Summary: | 15 Pág. Two distinct populations have been extensively studied in Atlantic cod (Gadus morhua L.): the Northeast Arctic cod (NEAC) population and the coastal cod (CC) population. The objectives of the current study were to identify genomic islands of divergence and to propose an approach to quantify the strength of selection pressures using whole-genome single nucleotide polymorphism (SNP) data. After applying filtering criteria, information on 93 animals (9 CC individuals, 50 NEAC animals and 34 CC × NEAC crossbred individuals) and 3,123,434 autosomal SNPs were used. This work was supported by The Research Council of Norway (Contract Number 245504), the Spanish Government Project (Grant Code CGL2012-39861-C02-02), and the INRA SELGEN funding metaprogram (Project GDivSelGen). Calculations were performed on the ABEL computer cluster at University of Oslo, Norway. Peer reviewed |
