Point mutation.
A5-A8 are transformed to A4, females lack genitalia, and there is a weak haploinsufficient transformation of A5-A8. Parasegments 10-13 are transformed to parasegment 9 in embryos.
dominant haplo-insufficient phenotypes, both sexes are partially or completely sterile. Lethal or nearly lethal over Df(3R)P9.
Fails to complement iab-5 and iab-6 alleles.
