Male gametocytes are called Spermatocyte and female gametocytes are called Oocytes. Each secondary spermatocyte will form two spermatids after Meiosis II. The primary spermatocyte is arrested after DNA synthesis and prior to division. The tail, or "flagellum", executes the lashing movements that propel the spermatocyte. Then each spermatocyte gives rise to four spermatids through meiosis.
