Females are weakly fertile. Egg chambers still have less than 15 nurse cells. When an oocyte is present the number of nurse cells is odd, whereas when there is no oocyte the number of nurse cells is even. Chambers with an oocyte frequently did not transfer nurse cell contents into the oocyte normally.
