Point mutation.
denticle & embryonic abdominal segment 9 | somatic clone
sclerite & abdominal segment 8 & embryo | somatic clone
A5-A8 (including female genitalia) transformed to A4 in mosaics. Embryos have sclerotic plates in pA8 and occasional extra denticles in A9, and parasegments 10-13 are transformed to parasegment 9.
Transformation of A8 to A7.
dominant haplo-insufficient phenotypes, both sexes are partially or completely sterile. Lethal or nearly lethal over Df(3R)P9.
Fails to complement all mutations in the Abd-B domain.
