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).
Scientists have speculated about the Y-chromosomal haplogroup (and therefore patrilineal ancestry) of Genghis Khan.
Zerjal et al. (2003) identified a Y-chromosomal lineage haplogroup C*(xC3c) present in about 8% of men in a region of Asia "stretching from northeast China to Uzbekistan", which would be around 16 million men at the time of publication, "if [Zerjal et al's] sample is representative." [1] The authors propose that the lineage was likely carried by male-line descendants of Genghis Khan, because of its presence in certain ethnic groups rumored to be their descendants. 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). [2]
A white paper by the American Society of Human Genetics Ancestry and Ancestry Testing Task Force, Royal et al. (2010) observed the Zerjal et al. hypothesis:
Although such a connection is by no means impossible, we currently have no way of assessing how much confidence to place in such a connection. We emphasize, however, that whenever formal inferences about population history have been attempted with uniparental systems, the statistical power is generally low. Claims of connections, therefore, between specific uniparental lineages and historical figures or historical migrations of peoples are merely speculative. [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. 2003).

Over the years, following haplogroups have been proposed as candidates: [5]
