Genetic studies on Iron Age individuals of the Shirenzigou site dated to circa 200 BCE have shown a fairly balanced admixture between the West Eurasian and East Eurasian genetic pools. The four extracted Y-DNA belonged to the following haplogroups:
Q1a1a1,
Q1a1b and
R1b1a1a2 (two samples). The samples of
mtDNA extracted belonged to haplogroups
U4’9,
T1a1b,
I1b,
U4,
G3b,
H15b1,
U5b2c,
U5a2,
