Stolarek et al: Genetic history of East-Central Europe...

[alexfritz]

So Kowalewko 38 and Czarnowko 547 appear not to be contaminated?

I suspect that all R-YP6048 samples from Stolarek et al. are contaminated (including Kowalewko 38) by someone who was in contact with the genetic material.

Out of 17 officially contaminated samples, 4 (!) belong to R-YP6048:
PCA0332 (BTW, labelled incorrectly as Ostrow Lednicki 322 by FTDNA)
PCA0333
PCA0403
PCA0496

PCA0038 (Kowalewko 38) has no Y-DNA calls in the .bam file - https://www.ebi.ac.uk/ena/browser/view/S...show=reads

not sure about the .bam file but in Table S3 there is a slot called 'Derived SNPs (Haplogroups:Marker: Position:Mutation)' to retrace the 'Terminal SNP' assignment and Kowalewko 38 is assigned R1a1a1b1a1a M458+

now whether YP6048 is a correct assignment or not remains to be seen, but Kow38 is nonetheless M458+ and not listed as contaminated in Table S1
rolling with that
