C2b1a1b/F3830
Rouran Khaganate

The mitochondrial haplotype of the TL1 individual was D4b1a2a1.
The Y‐chromosome haplotype was C2b1a1b/F3830 (ISOGG 2015), which was
the same as that of the other two ancient male nomadic samples (ZHS5 and
GG3) related to the Xianbei and Shiwei, which were also detected as F3889.

We conclude that F3889 downstream of F3830 is an important paternal lineage
of the ancient Donghu nomads. The Donghu‐Xianbei branch is expected to have
made an important paternal genetic contribution to Rouran. This component of
gene flow ultimately entered the gene pool of modern Mongolic‐ and Manchu‐
speaking populations.
