Parallel and nonparallel genome-wide divergence among replicate population pairs of freshwater and anadromous Atlantic salmon.

Abstract excerpt

Little is known about the genetic basis differentiating resident and anadromous forms found in many salmonid species. Using a medium-density SNP array, we documented genomic diversity and divergence at 2336 genetically mapped loci among three pairs of North American anadromous and freshwater Atlantic salmon populations. Our results show that across the genome, freshwater populations have lower diversity and a...
