The wing mutations,moreover, have been useful in checking up results obtained byremoval of part of the normal wings, while the differences in eyecolor have made possible a novel series of experiments on theeffects of lights of varying wave lengths. Finally, in one case it has been possible to study the directhereditary modification of a reaction system apart from any sig-nificant morphological variation. Although a considerable amount of work on the behavior
