Three Mongolian groups are included in the latest release of the YHRD Y-chromosomal database: Mongolia, Mongolia [Buryat], and Mongolia [Khalkh].
A search for the Mongolian modal haplotype (16-13-29-25-10-11-13-12,13) returned the following 62 matches, which seem to be confined to Altaic-speaking populations:
Ankara, Turkey: 1 / 39
Mongolia: 10 / 60
Mongolia [Khalkh]: 4 / 39
Taraz, Kazakhstan: 47 / 175
A search for the Buryat modal haplotype (16-14-30-23-10-14-14-11,13) returned the following 4 matches:
Gdansk, Poland: 1 / 543
Mongolia [Buryat] 3 / 42
The Mongolian [Khalkh] modal haplotype is the same as that of the Mongolian group, not surprising given the predominance of the Khalkh group in Mongolia.
The modal haplotype of the population from Taraz Kazakhstan is also the same as that of the Mongolian group. The Kazakhs are Altaic-speaking and exhibit the Turanid (mixed Caucasoid-Mongoloid) racial type.
