This sample was previously tested for
Y-chromosome and
mtDNA polymorphisms.
The pigmentation-related loci tested can be seen in
the labels of my post, which should lead you to some
earlier studies on them.
Most individuals were found to be most similar to
European than to East Asian or African individuals
based on these loci, although some (2 from
Andronovo)
of them were more similar to East Asians or
intermediate (1 from
Tagar) between East Asians and
Europeans.
Interestingly, 1 of the Andronovo Mongoloids (S07) was
previously found to belong to Y chromosome haplogroup
C(xC3), while the Caucasoid-Mongoloid individual from
Tagar (S32) belonged to haplogroup R1a1
(I.e even in unlikely
case the Andronovo Mongoloids were first generation immigrants, their kids were already a
mixture; try to extract from that Andronovo Mongoloid mixture purebred Indo-Iranians. The Tagar
crossbreed clearly carried his R1a1 from the Eastern European steppes, possibly for better
then 2 millennia.)
It should be noted that the use of
the term "European
individual ancestry" does not mean that these
individuals were from Europe, as no test to
distinguish between European and Asian Caucasoids was
performed, and we know from literary descriptions and
occasional archaeological remains about the ancient
presence of light-pigmented Caucasoids in Siberia
(The repeated
inferences to Indo-Europeans, Maria Gambitus, Europeans for Caucasoids are not only
misleading, but bring into scientific research an openly racial agenda).
From the paper:
The genotype for rs12913832 was obtained for 23
out of the 25 samples, and most had the G/G
genotype (n=15), which indicates that at least 60%
of ancient specimens were probably blue- or
green-eyed individuals. The remaining samples had
the A/G (n=5) or A/A (n=3) genotypes, which are
predictive of brown eye color phenotype.

Pigment phenotype and biogeographical ancestry from
ancient skeletal remains: inferences from multiplexed
autosomal SNP analysis
Caroline Bouakaze et al.
Abstract
In the present study, a multiplexed genotyping assay
for ten single nucleotide polymorphisms (SNPs) located
within six pigmentation candidate genes was developed
on modern biological samples and applied to DNA
retrieved from 25 archeological human remains from
southern central Siberia dating from the Bronze and
Iron Ages. SNP genotyping was successful for the
majority of ancient samples and revealed that most
probably had typical European
(i.e. Caucasoid, or are the
Italians and French atypical Europeans?) pigment features, i.e.,
blue or green eye color, light hair color and skin
type, and were likely of European
(i.e. Caucasoid) individual ancestry.
To our knowledge, this study reports for the first
time the multiplexed typing of autosomal SNPs on aged
and degraded DNA. By providing valuable information on
pigment traits of an individual and allowing
individual biogeographical ancestry estimation,
autosomal SNP typing can improve ancient DNA studies
and aid human identification in some forensic casework
situations when used to complement conventional
molecular markers.
