Washington, DC- Gene flow is not unique to genetically modified crops (GM), but the possible spread of transgenic DNA to wild and domesticated relatives raises a new set of issues for scientists and policymakers to consider, according to a new issue brief released today by the Pew Initiative on Food and Biotechnology.The brief, titled "Have Transgenes, Will Travel: Issues Raised by Gene Flow From Genetically Engineered Crops," summarizes the ecological and economic concerns experts mention when considering what could happen if novel traits from transgenic crops spread to other populations.<a href="http://pewagbiotech.org/resources/issuebriefs/geneflow.pdf">PEW Initiative briefing on gene flow</a>
