tgo5 clones (generated using the MARCM technique) of the ddaD and ddaC neurons do not show any obvious dendritic defects.
Mutant embryos have tracheal defects.
Close to a null allele. Homozygous clones have no effect in the proximal antennal segments (segments 1 and 2). Clones transform the distal part of antennal segment 3, the basal cylinder and arista to a tarsus that is deleted for most of its segments. Arista-claw intermediates are often present, and the identity of the proximal part of antennal segment 3 is unaffected. Homozygous clones in the distal part of the leg often show pattern deletions that include the second through fourth tarsal segments. Clones in the proximal part of the leg have no effect. Homozygous clones in the maxillary palps result in distal deletions. Homozygous clones in the wing hinge region cause the wing to be held out away from the body. Homozygous clones show a strong reduction in bristle size. Homozygous clones in the proboscis, vibrissae, dorsal head, dorsal thorax, wings and abdomen appear normal, with the exception of a reduction in bristle size.
