Animals zygotically mutant for pygo have normal cuticle patterning and survive until the third larval instar or early pupal stages.
pygounspecified mutants lack the eve positive RP2 neurons.
Mutant clones are typically smaller than their wild-type "twin spot" clones, although large mutant clones without any obvious defects can be obtained in the wing blade using the Minute technique. Eyes carrying mutant clones appear normal.
pygounspecified is a suppressor of visible | dominant phenotype of L2
Axnunspecified, pygounspecified has lethal | germline clone phenotype
pygounspecified is a suppressor of eye | ventral phenotype of L2
Axnunspecified pygounspecified double mutant germ-line clones only produces a few eggs that are not fertilised.
