- Detection of 1 haplogroup A* and 2 BCD chromosomes in Germany (3.2% non-Caucasoid paternal admixture)
- Detection of 1 E*(xE3b) chromosome in Austria (0.8% non-Caucasoid paternal admixture)
- Detection of 1 R1a*(xR1a1) chromosome in Norway; usually R1a chromosomes also harbor the defining mutation for R1a1, but it appears that this is not always the case.

A collaborative study of the EDNAP group regarding Y-chromosome binary polymorphism analysis
María Brion et al.
A collaborative study was carried out by the European DNA Profiling Group (EDNAP) in order to evaluate the performance of Y-chromosome binary polymorphism analysis in different European laboratories. Four blood samples were sent to the laboratories, to be analysed for 11 Y-chromosome single nucleotide polymorphisms (SNPs): SRY-1532, M40, M35, M213, M9, 92R7, M17, P25, M18, M153 and M167. All the labs were also asked to submit a population study including these markers.
All participating laboratories reported the same results, indicating the reproducibility and robustness of Y-chromosome SNP typing.
A total of 535 samples from six different European populations were also analysed. In Galicia (NW Spain) and Belgium, the most frequent haplogroup was R1b*(xR1b1,R1b3df). Haplogroup F*(xK) is one of the most frequent in Austria and Denmark, while the lowest frequency appear in Belgium.
Haplogroup frequencies found in this collaborative study were compared with previously published European Y-chromosome haplogroup data.
