CHROMOSOMES OF THE CHINESE MUSSEL ANODONTA WOODIANA (LEA 1834) (BIVALVIA, UNIONIDAE) FROM THE HEATED KONIN LAKES SYSTEM IN POLAND

摘要

The chromosome complement of freshwater mussel Anodonta woodiana was investigated using Giemsa, Ag-NOR and chromomycin A_3 staining. The diploid chromosome nμmber of this species is 2n = 38, and the arm nμmber (FN) = 76. Nucleolar organizer region (NOR) was found on one chromosome pair, and it was connected to GC-rich chromatin, as visualized by CMA_3 staining.
