21.3% of eggs laid by mxt^e00436/Df(2L)Exel6010 females mated to wild-type males fail to hatch. The embryos that fail to hatch show variable segmentation defects including deletion of one or more thoracic or abdominal segments, severe global defects or malformation or incomplete development of abdominal segments.

5-day old mxt^e00436/Df(2L)Exel6010 females produce approximately 80% as many eggs as controls, but the difference becomes more pronounced as the females age (mutant females laying only approximately 25% as many eggs as controls at 20 days old). The germaria of 21-day old mxt^e00436/Df(2L)Exel6010 females contain fewer germline cells than wild-type controls.
