It implies that the relationship between Japanese black cattle and Mongolian cattle is more distant. According to that the rate of sequence divergence of mtDNA is estimated to be 2% per million years, Haplotype II and III of mongolian cattle s mtDNA might be separate about 240 thousand years ago, which is earlier than the 10000-year history of cattle husbandry. Haplotype of yellow cattleand zebu cattle might be separate about 0.73-0.92 million years ago.
