Ancient genomic analysis of a Chinese hereditary elite from the Northern and Southern Dynasties.

Abstract

China's Northern and Southern Dynasties period (3rd-6th centuries AD) marked a significant era of ethnic integration in northern China. However, previous ancient DNA studies have primarily focused on northern ethnic groups, with limited research on the genetic formation of the hereditary elite family, especially considering their abundant archaeological record and clear material identity. In this study, we obtain the ancient genome of a hereditary elite family, Gao Bin (, 503 AD-572 AD), at 0.6473-fold coverage with 475,132 single-nucleotide polymorphisms (SNPs) on the 1240k panel. His mitochondrial haplogroup belongs to Z4 and Y-haplogroup to O1a1a2b-F2444∗. The genetic profile of Gao Bin is most similar to that of the northern Han Chinese. He can be modeled as deriving all his ancestry from Late Neolithic to Iron Age Yellow River farmers without influence from Northeast Asia, Korea, or the Mongolian Plateau. Our study sheds light on the genetic formation of hereditary elite families in the context of the Southern and Northern Dynasties ethnic integration.
