General Information
Term primary spermatocyte ID (Ontology) FBbt:00005286 (Fly Anatomy)
Definition Male germ cells of the 16-cell cyst from the end of the S-phase that precedes meiosis I to the end of meiosis I. This S-phase occurs very early in the 16-cell cyst stage so almost all 16 cell cysts are at the primary spermatocyte stage.[ FlyBase:FBrf0064778 ]
