Bridges fruit fly genetics research. US geneticist Calvin Blackman Bridges (1889-1938) seated in a laboratory at Columbia University Department of Biology, known as the 'fly room'. Bridges worked on sex-linked traits in the fruit fly (Drosophila melanogaster), producing results that suggested that chromosomes contained units of heredity (genes). Photographed circa 1920.
