Breakpoint(s) molecularly mapped
Breakpoint at DNA coordinate 58.8 to 59.6 (Campuzano et al., 1985).
Left limit of break 1 from polytene analysis (FBrf0042024) Right limit of break 1 from complementation mapping against ac (FBrf0003178) Limits of break 2 from polytene analysis (FBrf0039957)
In female D.simulans/D.melanogaster hybrids heterozygous for In(1)ac3 the anterior dorsocentral bristle and the posterior dorsocentral bristle are lost at a very high frequency.
Suppresses the expression of PgdA in larvae and adults.
