We present findings based on a study of Y-chromosome diallelic and microsatellite variation in 181 Icelanders, 233 Scandinavians, and 283 Gaels from Ireland and Scotland. All but one of the Icelandic Y chromosomes belong to haplogroup 1 (41.4%), haplogroup 2 (34.2%), or haplogroup 3 (23.8%). We present phylogenetic networks of Icelandic Y-chromosome variation, using haplotypes constructed from seven diallelic markers and eight microsatellite markers, and we propose two new clades. We also… Expand
mtDna and the islands of the North Atlantic: estimating the proportions of Norse and Gaelic ancestry.
TLDR
Admixture analyses indicate that the ancestral contributions of mtDNA lineages from Scandinavia to the populations of Iceland, Orkney, the Western Isles, and the Isle of Skye are 37.5%, 35. Expand
High level of male-biased Scandinavian admixture in Greenlandic Inuit shown by Y-chromosomal analysis
TLDR
Comparison of the European component of Inuit Y chromosomes with European population data suggests that they have their origins in Scandinavia, and the extreme sex bias in the admixture makes the later event more likely as the source. Expand
Genetic evidence for a family-based Scandinavian settlement of Shetland and Orkney during the Viking periods
TLDR
An extensive survey of Y-chromosomal and mitochondrial DNA variation in the North Atlantic region suggests that while areas close to Scandinavia, such as Orkney and Shetland, may have been settled primarily by Scandinavian family groups, lone Scandinavian males, who later established families with female subjects from the British Isles, mayHave been prominent in areas more distant from their homeland. Expand
Mitochondrial DNA variation in the Viking age population of Norway
TLDR
The combined analyses indicate that Norse women were important agents in the overseas expansion and settlement of the Vikings, and that women from the Orkneys and Western Isles contributed to the colonization of Iceland. Expand
Y-Chromosomal Diversity Suggests that Baltic Males Share Common Finno-Ugric-Speaking Forefathers
TLDR
The genetic similarity existing between Estonian, Latvian and Lithuanian men suggests that they originate from the same male founder population, and it is proposed that Baltic males share a common Finno-Ugric ancestry. Expand
The origin of the isolated population of the Faroe Islands investigated using Y chromosomal markers
TLDR
It is hypothesised that the high degree of Y chromosome similarity between the two populations arose because they were colonised at approximately the same time by males originating from the same regions of Scandinavia and, to a lesser extent, from the British Isles. Expand
Y chromosomal heritage of Croatian population and its island isolates
TLDR
High frequency of haplogroup I in Croatian populations and the phylogeographic pattern in its background STR diversity over Europe make Adriatic coast one likely source of the recolonization of Europe following the Last Glacial Maximum. Expand
A Reassessment of Genetic Diversity in Icelanders: Strong Evidence from Multiple Loci for Relative Homogeneity Caused by Genetic Drift
TLDR
Simulations indicate that genetic drift, and not admixture, is the most likely cause of the atypical Icelandic HVS1 frequency spectrum, and strongly indicate that the Icelandic gene pool is less heterogeneous than those of most other European populations. Expand
Highly discrepant proportions of female and male Scandinavian and British Isles ancestry within the isolated population of the Faroe Islands
TLDR
Compared to other admixed populations of the North Atlantic region, the population of the Faroe Islands appears to have the highest level of asymmetry in Scandinavian vs British Isles ancestry proportions among female and male settlers of the archipelago. Expand
Review of Croatian genetic heritage as revealed by mitochondrial DNA and Y chromosomal lineages.
TLDR
The aim of this review is to summarize the existing data collected in high-resolution phylogenetic studies of mitochondrial DNA and Y chromosome variation in mainland and insular Croatian populations, and reveal a clearly evident Slavic component in the paternal gene pool of contemporary Croatian men.

mtDNA and the origin of the Icelanders: deciphering signals of recent population history.
TLDR
The findings indicate that European populations contain a large number of closely related mitochondrial lineages, many of which have not yet been sampled in the current comparative data set, and substantial increases in sample sizes will be needed to obtain valid estimates of the diverse ancestral mixtures that ultimately gave rise to contemporary populations.

European Y-chromosomal lineages in Polynesians: a contrast to the population structure revealed by mtDNA.
TLDR
This is the first Y-chromosomal evidence of major European admixture with indigenous Polynesian populations and contrasts sharply with the picture given by mtDNA evidence. Expand
A Molecular Survey of Phenylketonuria in Iceland: Identification of a Founding Mutation and Evidence of Predominant Norse Settlement
TLDR
The molecular basis of phenylketonuria (PKU) is investigated in 17 Icelandic patients and 9 different mutations in the phenylalanine hydroxylase gene are found, almost exclusively Scandinavian background, and the complete absence of common Irish PKU mutations strongly support historical and linguistic evidence of a predominant Scandinavian heritage of the Icelandic people.

Y chromosomal DNA variation and the peopling of Japan.
TLDR
Four loci mapping to the nonrecombining portion of the Y chromosome were genotyped in Japanese populations from Okinawa, the southernmost island of Japan; Shizuoka and Aomori on the main island of Honshu; and a small sample of Taiwanese, confirming the irregular distribution of this polymorphism in Asia.

Recent male-mediated gene flow over a linguistic barrier in Iberia, suggested by analysis of a Y-chromosomal DNA polymorphism.
TLDR
Evidence for direct or indirect gene flow over the substantial linguistic barrier between the Indo-European and non-Indo-European-speaking populations of the Catalans and the Basques, during the past few thousand years is provided. Expand
Ancestral Asian source(s) of new world Y-chromosome founder haplotypes.
TLDR
The contrasting distribution patterns of the two major candidate founder haplotypes in Asia and the New World, as well as the results of a nested cladistic analysis, suggest the possibility of more than one paternal migration from the general region of Lake Baikal to the Americas. Expand
Y-chromosome polymorphisms and the origins of the European gene pool
TLDR
The clinal patterns and the estimated, recent separation times between populations jointly suggest that Y–chromosome diversity in Europe largely reflects a directional demic expansion, which is unlikely to have occurred before the Neolithic period. Expand
The central Siberian origin for native American Y chromosomes.
TLDR
This study suggests a predominantly central Siberian origin for Native American paternal lineages for those who could have migrated to the Americas during the Upper Pleistocene. Expand
Y-chromosome variation and Irish origins
TLDR
Ireland's position on the western edge of Europe suggests that the genetics of its population should have been relatively undisturbed by the demographic movements that have shaped variation on the mainland, but significant differences in genetic frequency between those of Irish Gaelic and of foreign origin are found.
