Abstract
Reddi, Reddy, and Rao1 have reported results of an experiment in which crossing-over was induced in Drosophila melanogaster males by injection of a saline extract of the ovaries of Drosophila. This communication summarizes the failure of two laboratories, operating independently, to repeat these experiments. In both laboratories efforts were made to adhere to the procedures described for preparation and injection of extracts. The assay systems were different and in both experiments they differed from that used by Reddi, Reddy and Rao1.
