Summary
1. Several acid amides, namely acetamide, propionamide, butyramide, caproamide and benzamide were found to increase the number of eye-facets in theGlued Stubble (Gl, Sb/LVM) andbrown (bw) mutants ofD. melanogaster when they are taken with the agar-molasses food.
2. Each acid amide had a limited range of concentration at which its facet activity is well marked. If the concentration is slightly above this range, the mortality becomes very high, due to the toxicity of the chemical agents.
3. The resistance of the two mutants towards the toxicity of the acid amides is the same.
4. All the amides so far examined have augmented the eye of thebrown mutant to the size or even larger than that of the wild eye. This can be regarded as a phenocopy of the wild type.
5. The effect of the acid amides is pronounced in the female but less distinct in the male.
6. The action of the acid amides would seem not to be directly connected with the operation of theBar gene.
