Multiple Selection Signatures in Farmed Atlantic Salmon Adapted to Different Environments Across Hemispheres.

ABSTRACT: Domestication of Atlantic salmon started approximately 40 years ago, using artificial selection through genetic improvement programs. Selection is likely to have imposed distinctive signatures on the salmon genome, which are often characterized by high genetic differentiation across population and/or reduction in genetic diversity in regions associated to traits under selection. The identification of such selection signatures may give insights into the candidate genomic regions of biological and commercial interest. Here, we used three complementary statistics to detect selection signatures, two haplotype-based (iHS and XP-EHH), and one F_ST-based method (BayeScan) among four populations of Atlantic salmon with a common genetic origin. Several regions were identified for these te
