Null phenotype. Antennal transformations, reduction in bristle size and tarsal deletions.
flies are viable and fertile, and have a modest aristapedia phenotype; the proximal portion of the arista is swollen and carries bracted bristles characteristic of the tarsus. Bracted bristles are also found on the distal portion of the third antennal segment. ssa
flies have an aristapedia phenotype; the arista and part of the third antennal segment are transformed into a well formed distal leg carrying 2 claws and 3 to 4 tarsal segments. ssaP88
is viable in transheterozygous combination with either ssaC6
, and gives the following phenotype; flies show complete transformation of the distal antenna to distal tarsus. Bristles show and extreme and consistent spineless phenotype. Fusions of most of the tarsal segments of the legs and also of the transformed aristapedia tarsus are seen. ssaP88
is viable in transheterozygous combination with either ssaC5
producing flies with an aristapedia phenotype.
