Comparative genomic analysis of Atlantic salmon, Salmo salar, from Europe and North America
BioMed Central Background: Several lines of evidence including allozyme analysis, restriction digest patterns and sequencing of mtDNA as well as mini- and micro-satellite allele frequencies indicate that Atlantic salmon (Salmo salar) from North America and Europe are genetically distinct. These obse...
