Genetic descent from Genghis Khan
With the advent of genealogical DNA testing, a larger and broader circle of people have begun to claim genetic descent from Genghis Khan owing to dubious and imprecise haplogroup identifications.However, while many of Genghis Khan's agnates' resting places are known (e.g. Shah Jahan in the Taj Mahal), none of their remains have been tested to prove or disprove these theories and debate continues (see below).One study published in the Russian Journal of Genetics found that 24% of Mongolians carry this haplogroup, and that it occurs in low frequencies in neighboring Turkic states (with the exception of Kazakhstan).We emphasize, however, that whenever formal inferences about population history have been attempted with uniparental systems, the statistical power is generally low.[3]In a 2017 review paper published in Human Genetics, authors Chiara Batini and Mark Jobling cast doubts on Zerjal's 2003 theory that Genghis Khan is linked to haplogroup C: Ancient DNA data (Lkhagvasuren et al. 2016) from remains in high-status Mongolian graves dated to 1130–1250 CE revealed MSY lineages belonging to hg R1b, rather than hg C: there are a number of explanations for such findings, but taken at face value, they do not support the Genghis Khan hypothesis for the origin of the widespread Asian expansion lineage (Zerjal et al.
