On tomorrow's Science Friday program, host Ira Flatow will discuss the etymology of the word "genome" with the University of Michigan's Howard Markel, as part of the show's monthly Science Diction series. Markel says that "much of our 'genetic' terminology stems from the Greek word, genesis." In 1920, Hans Winkler "collided the German word for gene, gen, with the Greek suffix, -om, indicating body — from soma," he adds.
