The agency treats genetically engineered products as though they pose some inherent, systematic, unique risks, when theoretical considerations, risk-assessment experiments and practical experience make it clear that they do not: A quarter-century-old scientific consensus holds that the molecular techniques of genetic engineering are an extension, or refinement, of less precise and predictable techniques for genetically improved products with which consumers and government regulators have long familiarity and comfort.

Never mind that numerous professional medical and scientific societies around the world had concluded as early as the 1980s that the new molecular techniques of genetic engineering posed no greater risks to health or environment than other products.

FORBES: Precaution Without Principle

Using new genetic techniques such as molecular mapping, they have located a set of genes on one chromosome that appears to control the process in a grass species called Tripsacum.
