Y chromosome variation in 457 Croatian samples was studied using 16 SNPs/indel and eight STR loci. 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. The higher frequency of I in the southern island populations is contrasted with higher frequency of group R1a chromosomes in the northern island of Krk and in the… 

Review of Croatian genetic heritage as revealed by mitochondrial DNA and Y chromosomal lineages.

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.

Y chromosomal haplogroup J as a signature of the post-neolithic colonization of Europe

Dating estimates confirmed the presence of a major population structuring at the time of spread of haplogroup J in Europe and a punctuation in the peopling of this continent in the post-Neolithic, compatible with the expansion of the Greek world.

Maternal Genetic Heritage of Southeastern Europe Reveals a New Croatian Isolate and a Novel, Local Sub‐Branching in the X2 Haplogroup

The results of 1035 samples show that the SEE maternal genetic diversity fits within a broader European maternal genetic landscape and shows that the population of Žumberak, located in the continental part of Croatia, developed some unique mtDNA haplotypes and elevated haplogroup frequencies due to distinctive demographic history and can be considered a moderate genetic isolate.

the genetic landscape of Serbian populations through mitochondrial DNA sequencing and non-recombining region of the Y chromosome microsatellites.

On the whole, the genetic variability of the Balkan populations seems to be due to an admixture process of European and Asian lineages in different proportions whose contributions constitute the current maternal and paternal genetic landscape.

Excavating Y-chromosome haplotype strata in Anatolia

This comprehensive characterization of Y-chromosome heritage addresses many multifaceted aspects of Anatolian prehistory, including: the most frequent haplogroup, J, splits into two sub-clades, one of which (J2) shows decreasing variances with increasing latitude, compatible with a northward expansion.

Distinguishing the co-ancestries of haplogroup G Y-chromosomes in the populations of Europe and the Caucasus

No clinal patterns were detected suggesting that the distributions are rather indicative of isolation by distance and demographic complexities, and the P303 SNP defines the most frequent and widespread G sub-haplogroup.

Y-Chromosome haplogroup I prehistoric gene flow in Europe

To investigate which aspects of contemporary human Y-chromosome variation in Europe are characteristic of primary colonization, late-glacial expansions from refuge areas, Neolithic dispersals or more

Genetic Comparison of a Croatian Isolate and CEPH European Founders

It is concluded that genotyping arrays should perform equally well in an isolate as in outbred European populations for disease mapping studies and that SNP–trait associations discovered in the authors' well‐characterized Croatian isolate should be valid in the general European population from which they descend.

High-resolution phylogenetic analysis of southeastern Europe traces major episodes of paternal gene flow among Slavic populations.

The extent and nature of southeastern Europe (SEE) paternal genetic contribution to the European genetic landscape were explored based on a high-resolution Y chromosome analysis involving 681 males from seven populations in the region, finding that five major haplogroups comprise more than 70% of SEE total genetic variation.

Divergent patrilineal signals in three Roma populations.

Y-chromosome distributions in three Roma collections residing in Belgrade, Vojvodina and Kosovo are reported for the first time and illustrate that the most notable difference among the three Roma populations is in their opposing distributions of haplogroups H and E.



The evidence of mtDNA haplogroup F in a European population and its ethnohistoric implications

The first published phylogenetic analysis of haplogroup F worldwide is presented, applying the median network method, suggesting several scenarios how this maternal lineage may have been added to the Croatian mtDNA pool.

MtDNA haplogroups in the populations of Croatian Adriatic Islands.

As the settlements on the islands were formed trough several immigratory episodes of genetically distant populations, this analysis showed greater genetic diversity than expected at the level of particular settlements.

European Y-chromosomal lineages in Polynesians: a contrast to the population structure revealed by mtDNA.

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.

Y-chromosomal diversity in Europe is clinal and influenced primarily by geography, rather than by language.

These patterns retain a strong signal of expansion from the Near East but also suggest that the demographic history of Europe has been complex and influenced by other major population movements, as well as by linguistic and geographic heterogeneities and the effects of drift.

Y chromosomal DNA variation and the peopling of Japan.

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.

Genetic epidemiological studies of eastern Adriatic Island isolates, Croatia: objective and strategies.

Four illustrative examples of research opportunities which are afforded by the unique circumstances found in these isolate communities related to hereditary dwarfism on Krk island, Mal de Meleda on Mljet island, extreme inbreeding on Susak island and population genetics of cancer on the islands of Brac, Hvar, Korcula, Vis and Lastovo are presented.

Y-Chromosomal Diversity Suggests that Baltic Males Share Common Finno-Ugric-Speaking Forefathers

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.

Estimating Scandinavian and Gaelic ancestry in the male settlers of Iceland.

Results based on a study of Y-chromosome diallelic and microsatellite variation in 181 Icelanders, 233 Scandinavians, and 283 Gaels from Ireland and Scotland indicate closer matrilineal links with populations of the British Isles, which supports the model, put forward by some historians, that the majority of females in the Icelandic founding population had Gaelic ancestry.

Factors affecting population variation in eastern Adriatic isolates (Croatia).

Genetic, morphological, kinship, and language distance data is used, collected for individuals from 26 rural communities on the islands of Brac, Hvar, Korcula, and the Peljesac Peninsula in the Adriatic, to further explore the interaction of historical, sociological, and biological factors in small populations and to test the significance of some of these proposed causes.
