汉语语境:
考古学家对陕西泉护村遗址出土的距今3000年左右的8个黄牛遗骸进行了线粒体DNA分析，成功地获得了5个古代黄牛序列。泉护村黄牛由T3和T4世系组成，其中T3世系占统治地位（占百分之八十80）。中介网络分析，泉护村黄牛与5个北方早期青铜时代遗址古代黄牛密切相关，极有可能来自上述地区。此外，主成分分析表明泉护村黄牛与现代中国北方组黄牛的遗传关系最近，遗传结构呈现连续性。
英语语境:
Archeologists conducted mitochondrial DNA analysis on eight cattle remains excavated from Quanhucun site dating to around 3000 years ago, and successfully obtained five sequences. The sequences of ancient cattle were composed of haplogroups T3 and T4, of which T3 was dominant (accounting for 80 percent). Phylogenetic network analysis indicated that Quanhucun cattle were relative to ancient cattle from five Early Bronze Age archaeological sites in Northern China, and may be from those areas. In addition, principal component analysis suggested that Quanhucun cattle had a close affinity to modern cattle in Northern China by presenting a continuity of genetic structure.
