Western Norway, being relatively remote from the European continent and the known source of Viking migrations is of special anthropological interest. It may represent a relatively untainted North Germanic gene pool, and is usually thought to be a good representative of the Norsemen of the Viking age.
The modal haplotype of W. Norway is 14-12-28-23-10-11-13-14,14 and according to Whit Athey's haplogroup predictor it is suggestive of Y-haplogroup I1a which has a well-known Northwestern European main distribution. Its prevalence in Europe (129 matches) is shown below:
The distribution of a one-step neighbor of the above (14-12-28-23-10-11-13-13,14) with 105 occurrences in Europe has the following distribution:
