Abstract
The distribution of Y-chromosomal haplogroup G2a (G-P15) in present-day paternal lineages in Tyrol
(Austria) was analyzed by applying a high-density regional sampling scheme that also covered remote
mountain areas. There is evidence from ancient genetic data for a high frequency of Y-chromosomal
haplogroup G in prehistoric populations of Central Europe, whilst nowadays levels well below 10% are
routinely observed. A population sample comprising 3700 specimens was analyzed for Y-chromosomal
variation by genotyping Y-SNPs and Y-STRs. The set of binary markers included nine SNPs specific for
sub-lineages of haplogroup G. The frequency of haplogroup G in 2379 unrelated men born in Tyrol
amounted to 11.3%. Nearly all of these Y chromosomes belonged to haplogroup G2a. The main subhaplogroup
within G2a was defined by the SNP L497 (G2a3b1c) and reached a population frequency of
8.6%. Although this average level is higher than reported for other countries the geographical distribution
of haplogroup G-L497 showed a differentiated pattern with a clustered distribution within some alpine
valleys, where maxima above 40% were found. Both, the estimation of coalescent times and a principle
coordinates analysis based on RST values derived from Y-STR haplotypes from different sub-regions of
Tyrol revealed evidence for an old settlement history associated with Y chromosomes belonging to
haplogroup G in the Tyrolean Alps.

I read this article, interesting

80% of the G marker in the Tyrol ( north, south and east ) is L497

otzi was L91 which is only 1%

Ibiza has 18% of L497

Veneto between 4 -12%

It also states that the marker originated in central Europe in the alps................is it a Rhaetic marker , maybe Celtic or Venetic ?
