most recent update:

a few potentially interesting side notes on probably originally North Asian Hazara mtDNA hgs in two so far known samples:
- C4a1: relatively common in both the Quetta and Afghanistani samples
- D4b: less common in the Quetta samples than in Buryat and SE Mongolian samples
- D4c: relatively common in the Quetta samples
- D4j: less common in the the Quetta samples than in Buryat and SE Mongolian samples

Since relatively many of the y-chromosomal samples from the so far examined Quetta and Afghanistani Hazara communities turned out to be in one probably originally Mongolian cluster, the major North Asian mtDNA hgs of the same Hazara communities might have Mongolian backgrounds as well. In this sense, the apparent relative abundance of D4c and the relative lack of D4b and D4j in the Quetta Hazara sample of Rakha et al. might imply a partial mtDNA profile Quetta Hazaras could have in common with Khalkh communities in particular. Anyway, there is a lack of genetic studies on Khalkhs in general. So future studies will have to clarify.




1st update:

new paper: Wei Lanhai et al. 2018: "Whole-sequence analysis indicates that the Y chromosome C2*-Star Cluster traces back to ordinary Mongols, rather than Genghis Khan"; doi: 10.1038/s41431-017-0012-3

They provide some more insight into mainstream research. From the "heritage" passage in their doc file:
Quote:
 
Before and after the foundation of the Mongol Empire, people of Niru'un Mongol were the core components of the Khanate’s upper classes and provided most of soldiers and generals of army. Participating in the conquest of Genghis Khan, they scattered (...).


The history of the social structures of the Mongolian-descended Hazara lineage communities could, thus, be compared with those of Dughlat, Keneges and Manghit communities.




old post:

see the MJN in supplementary fig. 4C of Zhabagin et al. 2017: one major Hazara ht appears to split from one major Dughlat ht, whereas another major Hazara ht seems to split from one major Kerey ht. So the according lineages probably have different histories even though both of them belong to the same medieval starlike cluster.

The y ht data of Di Cristofaro et al. 2013 and Haber et al. 2012 might clarify which lineages might belong to which particular Hazara local groups and could give clues as for what kind of pre-histories Hazara local groups possibly had in this context. Apparently, the possibly more Kerey-related Hazara lineages partly became Uzbek. I.e., they might belong to Hazara communities which mixed with Uzbek communities. By contrast, the possibly more Dughlat-related Hazara lineages appear to have managed to maintain a distinctive Hazara cluster. So the latter might have maintained Mongolian identities for a longer period of time.
