  • ND, not determined.

  • a The average number of cysts per germarium that contained MEI-P22-staining nuclei in nurse cells and/ or pro-oocytes. In wild type usually only one cyst had pro-oocyte staining whereas in the mutants most cysts had pro-oocyte staining.

  • b The number of germaria that had MEI-P22 staining in at least one region 2b cyst.

  • c The average number of foci in the two cells in each region 2a cyst with four-ring canals and complete SC formation (pachytene) that also had MEI-P22 foci.
