Popis:	The Ag-pattern of amplified nucleolar material in various stages of R. lucifugus oogenesis has been followed. At zygotene a nucleolar mass is associated with chromosomal nucleolar organizer regions. At pachytene small brown extra nucleoli are interspersed among the bivalents. At early diplotene the microuncleoli fuse into larger nucleoli. During the late stage of oogenesis large masses of silver stainable material (ribonucleoprotein aggregates) are released in the cytoplasm.
