InGen, short for International Genetic Technologies, created the dinosaurs in "Jurassic Park." The fictional bioengineering company was founded by industrialist John Hammond and developed a method for recreating extinct animals.
In the story, InGen scientists extract fragments of dinosaur DNA from mosquitoes preserved in amber. Because the recovered genetic material is incomplete, they fill gaps with DNA from living animals, including amphibians. The resulting creatures are genetically engineered reconstructions rather than perfectly restored dinosaurs, an important detail that explains some of their unexpected traits.
InGen's research and breeding operations are centered on fictional islands near Costa Rica, especially Isla Nublar and Isla Sorna. The company intended to display its creations at a dinosaur theme park, but containment failures caused the original park to collapse. A frequent mix-up is confusing InGen with BioSyn: BioSyn is a rival company associated with Lewis Dodgson, while InGen is the company that created the original park's dinosaurs.
