The yellow-necked mouse, Apodemus flavicollis, is characterized by a frequent occurrence of B chromosomes. The frequency of intra individual mosaicism of Bs was studied in 995 animals collected at six localities in Serbia. It was found that 329 (33.06%) possessed B chromosomes. Among these, 87 animals (26.44%) were mosaics. A total of 32 mosaic animals with more than one B chromosome were analyzed for distribution of Bs which was found to be quite different between groups of animals with different numbers of Bs and increases with their number. The frequency of mosaics differs between localities and ranges from 0.22 to 0.55.
