Ets97D⁹⁰²/Df(3R)ro80b and Ets97D⁶¹³/Ets97D⁹⁰² flies die as pharate adults. Ets97D^tne-1 is viable but female sterile in transheterozygous combination with Ets97D⁹⁰². Ets97D^tne-1/Ets97D⁹⁰² females have some abnormalities in oogenesis, although the majority of eggs laid by these females appear morphologically normal. Approximately 15% of these eggs develop to late stage embryos, a small percent of these hatch into first instar larvae and in rare cases some animals develop to the adult stage. The embryos have defects in abdominal segmentation, ranging from mild defects in segments A4 to A7, to broad fusion and/or deletion of segments including A2 to A7.
