Abstract

The chromosome theory of heredity opened a large field for both cytologists and geneticists. They looked to the day when someone would find an organism in which the chromosomes were so large that it would be possible to see Qualitative differences along their length corresponding to the different genes which they knew must be present at these points. Before 1932, methods and materials to show these chromosomes to any appreciable extent had, however, not yet been devised. Competent observers using the finest of optical equipment, and the most refined techniques of staining could see little at the time of nuclear division. Theophilus S. Painter, of the University of Texas; Calvin G. Bridges and C. W. Metz of the Dept, of Embryology, Carnegie Institution of Washington, Baltimore, Md., and other well known observers have since given to the world an interesting and accurate understanding of the chromosome—its organization; its structure; the position of its genes.
