|Phenotype Manifest In|
Null phenotype. Antennal transformations, reduction in bristle size and tarsal deletions.
ssaP88 in combination with ssa, ssaB, ssax or ssa40a produces transformation of the arista to distal mesothoracic tarsus. The expressivity of the phenotype decreases with increasing temperature in ssaB/ssaP88 flies. A high proportion of ssa40a/ssaP88 or ssa/ssaP88 flies produce an ectopic tarsal response to chemical stimulation at 25oC. ssa/ssaP88 and ssax/ssaP88 flies usually cannot fly, although ssaB/ssaP88 and ssa40a/ssaP88 flies often show some flight ability.
ssaC3/ssaP88 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/ssaP88 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, ssaC10, ssaC11, ssaC13, Df(3R)ss-a or ssaC16, 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, ssaC7, ssaC8, ssaC9, ssaC12 or ssaC14 producing flies with an aristapedia phenotype.
