Recent spread of a Y-chromosomal lineage in northern China and Mongolia

We have identified a Y-chromosomal lineage that is unusually frequent in northeastern China and Mongolia, in which a haplotype cluster defined by 15 Y short tandem repeats was carried by similar to 3.3% of the males sampled from East Asia. The most recent common ancestor of this lineage lived 590 +/- 340 years ago (mean +/- SD), and it was detected in Mongolians and six Chinese minority populations. We suggest that the lineage was spread by Qing Dynasty (1644-1912) nobility, who were a privileged elite sharing patrilineal descent from Giocangga (died 1582), the grandfather of Manchu leader Nurhaci, and whose documented members formed similar to 0.4% of the minority population by the end of the dynasty.
