In an analysis of salmon samples collected by students in their local stores and restaurants, DNA sequencing and phylogenetic analysis were used to detect market substitution of Atlantic salmon for Pacific salmon. This allowed students to apply molecular methods such as polymerase chain reaction (PCR) and DNA sequencing to a socially relevant issue.Undergraduate Introductory Biology EducationSalmon Market SubstitutionPhylogenetic AnalysisDNA SequencingPolybrominated Diphenyl EthersGlobal AssessmentWild SalmonContaminantsSeafood10.1525/abt.2012.74.4.7
