Dominant Contribution of Northern Chinese to the Paternal Genetic Structure of Chaoshanese in South China
2011
We investigated the Y chromosome of various Chinese populations to determine the patrilineal origin of the Chaoshanese population. Admixture analysis of six specific Y short tandem repeat (STR) loci in 6,292 individual samples taken from 51 populations, including Chaoshanese and Minnanese of our earlier studies, showed that over 85% of the Chaoshanese Y chromosomes were derived from the Central China Han (M RH: 0.8614; M BE: 1.1868 ± 0.2054), and a very small portion were from the southern aborigines. These results support a Central China Han origin of the Chaoshanese and additionally reveal that males from the Central China Han were the predominant contributor to the patrilineal genetics of the Chaoshanese. A phylogenetic tree and analysis of molecular variance signified a strong association between Y chromosomes of Chinese populations and their linguistic affiliations, revealing a coevolution of Y chromosome diversity and languages in East Asia.
