Y-chromosomal variation at five biallelic markers (Tat, YAP, 12f2, SRY10831 and 92R7) and nine multiallelic short tandem
repeat (STR) loci (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385I/II and DYS388) in a
Norwegian population sample are presented. The material consists of 1766 unrelated males of Norwegian origin. The
geographical distribution of the population sample reflects fairly well the population distribution around the year 1942, which
is the median birth year of the index persons. Seven hundred and twenty-one different Y-STR haplotypes but 726 different
lineages (Y-STRs plus biallelic markers) were encountered. We observed six known (P*(xR1a), BR(xDE, J, N3, P), R1a, N3,
DE, J), and one previously undescribed haplogroup (probably a subgroup within haplogroup P*(xR1a)). Four of the haplogroups
(P*(xR1a), BR(xDE, J, N3, P), R1a and N3) represented about 98% of the population sample. The analysis of population
pairwise differences indicates that the Norwegian Y-chromosome distribution most closely resembles those observed in Iceland,
Germany, the Netherlands and Denmark. Within Norway, geographical substructuring was observed between regions and
counties. The substructuring reflects to some extent the European Y-chromosome gradients, with higher frequency of P*(xR1a)
in the south-west and of R1a in the east. Heterogeneity in major founder groups, geographical isolation, severe epidemics,
historical trading links and population movements may have led to population stratification and have most probably contributed
to the observed regional differences in distribution of haplotypes within two of the major haplogroups.
BR*(xDE, J, N3, P)" включает в себя I1a и практически из нее одной и состоит.
P*(xR1a) состоит практически из R1b.
http://vetinari.sitesled.com/norway.pdfWestern Norwegian modal haplotypeWestern 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:
