Pharate pupae and the few eclosing adults show a short leg phenotype. Leg length = 40% wild type. Tibia-tarsal joints remain but other joints are lacking. Heterozygotes with AP-29 or AP-210 have normal or nearly normal legs and moderate incidences of necrotic joints and ectopic cuticular elements with sensory structures that invade medioventral eye territory. In rare instances in AP-28/AP-210 flies supernumerary antennae develop and the adjacent eye is reduced.
Alleles fall into an allelic series based on leg length defect. In order of decreasing severity of phenotype: AP-22 = AP-23 = AP-24 = AP-25 = AP-213 = AP-214 = AP-215 = AP-216 = AP-219 > AP-28 = AP-212 > AP-211 > AP-217 > AP-218 > AP-210 = AP-29.
