"In the gene pool of Northern Altaians, it is the
second most frequent haplogroup /Q/ after R1a1 (22%); in
Southern Altaians, the proportion of this haplogroup /Q/ is
significantly lower (4%). In earlier studies, haplogroup
Q* with different frequencies was described in most of
Siberian ethnic groups. With low frequency (1 to 17%;
with the average of 5%) this haplogroup is found in
Middle and Central Asia, India, and Siberia [27, 53].
High frequencies of haplogroup Q* are detected among
Native Americans (up to 25%), where it is the second
most frequent haplogroup after its derivative, haplo-
group Q3 . In Siberia, this haplogroup accounts for
the lion’s share (66%) of the Selkup gene pool ,
while the highest Q* frequency was detected in Kets
(94%). In other parts of the region the Q* frequency
varies in the range from 5 to 15%. It is suggested that
peak frequency of haplogroup Q* in the region of con-
temporary residence of Kets and Selkups does not point
to this region as to the center of origin of this haplo-
group. It is known that presumptive motherland of the
ethnic groups mentioned above is located in South
Siberia, where their ancestors are thought to have pen-
etrated from Central Asia [55, 56]. These data are con-
sistent with the information on the significant participa-
tion of the Samoyedic ethnic groups in the ethnogeny of
