Transplantation in Drosophila

The application of the method of transplantation, which has been so fruitful in the study of many biological problems, to genetically well known material, has advantages which are at once apparent to those who have thought about questions concerning the relation of genes to the developmental process. In this communication we wish to present, in a preliminary way, certain results obtained by the use of a technic which we have developed specifically for the transplantation of organs of Drosophila.
