云南bo人源流的父系和母系遗传研究
The Genetic Study on the Patrilineal and Matrilineal Origin of the Bo People in Yunnan
-
摘要: 对云南bo人32份男性DNA样本进行Y染色体单倍型以及mitochondrial DNA (mtDNA)单倍型分析，结果发现云南bo人的父系和母系遗传组分都表现出典型的南方人群的遗传特征。由bo人的数据结合已经发表的东亚人群的Y染色体和mtDNA单倍型(haplotype)数据进行Multidimensional Scaling(MDS)分析，结果表明，在MDS分布图中bo人群体的Y染色体单倍型和mtDNA单倍型都与南方人群聚在一起。这一结果支持bo人的遗传族源为东亚南方人群后裔，与考古学的推论相一致。结合历史和考古学证据来探讨bo人的起源和史前迁移，为揭开“bo人悬棺”这种独特的考古文化的起源和史前传播提供遗传学的研究证据。Abstract: The Y chromosome and mtDNA from 32 male samples of Bo people were typed. The results showed that the Bo people originated from the south of China possessing the dominant patrilineal and matrilineal haplotypes that are prevalent in the southern East Asian populations. The multidimensional scaling analysis on the Bo people's hapoltypes, combined with published Y chromosome and mtDNA data from East Asian populations, demonstrated that the Bo people are genetically closer to the southern populations than to the northern. This indicates that the Bo people are descendants of a southern China origin population, which is consistent with archeological evidence. The genetic dissection of the Bo people sheds new light on the origin and dispersion of the prehistoric "cliff coffin" culture.
