Abstract
Prometaphase preparations have been used to construct a ‘standard’ RBA-banded karyotype of the swamp buffalo (Bubalus bubalis L., 2n = 48) and to compare the banding homologies between buffalo and cattle (Bos taurus L.). A double numbering system, one progressive and one corresponding to the standardized nomenclature of cattle chromosomes, has been used in order to facilitate banding pattern comparisons between the two species. Evolutionary relationships between Asiatic buffalo and European cattle have been also examined on the basis of the RBA and C-banding pattern of the X and Y chromosomes of the two species.
