In wasps mosaic for stumpy or fused legs, both type and mutant tissues were apparently modified. Stumpy was more frequently and more extremely modified when type was present on the same side of the body than when it was present on the opposite side only. This indicates a closer physiological relationship of tissues on the same side of the body than of tissues on opposite sides. In mosaics mesothoracic legs were most often modified, but metathoracic legs were more extremely modified. Legs of gynandromorphs were more modified than legs of male mosaics.
In wasps mosaic for ivory eye colour, type tissue in either eye is almost always accompanied by orange or modified tissue, where ivory is expected. An eye, mosaic for type and ivory, shows grading from black to orange. Even when type tissue is not present in the eyes, the colour is usually not ivory but light peach, light orange or darker orange. Wasps mosaic for cantaloup or white or both, typically show no interaction of the two tissues involved. In three cases there was modification.
Among wasps mosaic for honey and stumpy 26 per cent. must be explained as cases of mixing of tissues, of extreme modification, or trinuclearity.
