Abstract

There are three major groups of domestic cattle in East and Southeast Asia: European cattle, Zebu cattle, and Bali cattle. Ten restriction enzymes were used to analyze restriction site variants in the mitochondrial DNA (mtDNA) in 178 individuals belonging to these three groups of cattle. The results indicate that each of the three groups has mtDNA with a specific haplotype. The sequence of the mitochondrial gene for cytochrome b in representative haplotypes of Zebu and Bali cattle was determined and was compared with that of European cattle in the literature. We calculated 51 pairwise nucleotide sequence differences between European and Zebu cattle and 91 between European and Bali cattle. Our results suggest that ancestral populations of Asiatic domestic cattle may have diverged into two lineages--Bali and European plus Zebu--more than 3 million years ago, and then the European and Zebu groups diverged more than 1 million years or so before domestication occurred.
