Irregular reduction of abdominal tergites, sternites, pigmentation and bristles; more marked in females and increased by crowding and dry food (FBrf0004149). Schaffer's data (FBrf0003298) suggest irregular dominance in heterozygote, overlapping of wild type in homozygote and genetic modifiers. RK3.
Allelism inferred from similarity in genetic location and phenotype and incomplete complementation.
