The electrophoretic variation in bovine hemoglobin-beta (HBB) is one of the most investigated genetic markers. The presence of a unique HBB variant, HBBX, in Southeast Asian cattle has been reputed as a sign of gene-flow from wild bovine species. In this study, we analyzed the DNA sequences of HBB genes in domestic and wild bovine species to verify this belief. Isoelectric focusing of HBB chain revealed that the HBBX in domestic cattle had dimorphism and was separated into HBBX1 and HBBX2. The HBBX1 had the same DNA sequence of the common HBB variant in gayal (Bos gaurus frontalis), while some of the HBBX2 were identical with that of Cambodian banteng (Bos javanicus birmanicus). As a result, we confirmed that the bovine HBB variants can be a good indicator of introgression between wild and domestic cattle. The HBBX1 was always predominant to HBBX2 in the continental populations, suggesting that the gaur had contributed to the gene pool of domestic cattle in this region much more than the banteng. On the other hand, the mitochondrial DNA analysis could not detect gene-flow from wild species. Autosomal markers that can trace the phylogeny between alleles are suitable for the assessment of bovine interspecific introgression.
