      Reference

      Egg chambers are formed but the cells within the chambers are morphologically abnormal and degenerate before yolk uptake begins.

      (Schupbach and Wieschaus, 1991)

      female-sterile Homozygous females often have underdeveloped ovaries which seem to lack germ cells altogether. In some females a small number of developing egg chambers is found; may contain abnormal numbers of nurse cells and never develop beyond the first few stages of oogenesis.
