tud mutant embryos were produced by females transheterozygous for the respective tud mutation and tud deletion(Df(2R)PurP133, see Materials and methods). Wild-type control embryos were from tud+/Df(2R)PurP133mothers.
The number of germ cells was not determined (ND) because very few embryos form germ cells.
