利用古DNA技术从15个二里头遗址出土黄牛个体样本中得到9个个体mtDNA Dloop环序列。全部为普通牛,7个个体为T3世系,另外两个个体分别为T2世系和T4世系。二里头黄牛的所有单倍型在中国现代地方黄牛品种个体中存在并且广泛分布,表明经历数千年的时间,中原地区古代黄牛的基因稳定地遗传下来。
Nine individual mtDNA Dloop loop sequences were obtained from ancient cattle samples from 15 Erlitou sites using ancient DNA techniques. All were normal cattle, 7 individuals were T3 lineage, and the other two were T2 lineage and T4 lineage respectively. All haplogroups of Erlitou cattle exist and widely distributed in modern Chinese local cattle breeds, indicating that the genes of ancient yellow cattle in the Central Plains have been stably inherited over thousands of years.
