The genetic polymorphism of an entire Bov‐A2 element located in the second intron of the buffalo and bovine k‐casein ( CSN3 ) gene was investigated by amplification and sequencing of PCR products. Single nucleotide polymorphisms were detected. A PCR‐RFLP method was developed to detect an A or G mutation at position 605 of bovine Bov‐A2 element which creates a Bfa I polymorphic site. The frequencies of the B allele, with the Bfa I site, were for 0·275, 0·775, 0·750, 0·975, respectively, for Italian Holstein Friesian, Grey Alpine, Friuli Red Pied and Reggio bovine breeds. The mutation rate (substitutions and deletions/insertions per nucleotide site per year) was 2·5 × 10−9 for Bov‐A2 sequences in the second intron of CSN3 . The comparison with other Bov‐A2 elements suggests that this retroelement might be an important source of single nucleotide polymorphism for analysis of Bovidae genomes.
