Abstract
An inner portion of chromosome III became inserted near locus 3 in the X-chromosome. [male][male] with 2 normal 3d chromosomes + the inserted fragment resemble facet for extended wings, occasionally nicked wings, and tendency for rough eyes; [female][female] with the duplication resemble facet only for extended wings, but when present with notch show the same exaggerated characteristics, except for eyes, as do notch/facet [female][female]. Flies carrying the trans-location are not facet-like due to a suppressor located at the fragmented point of chromosome III. The suppressor is interpreted to be a small piece of X, including non-facet, which had interchanged with the fragment of 3. [male][male] with the duplication of 3 are deficient for the piece of X. It is suggested that the gene facet may be a deficiency.
