"The two Y haplogroups, J & E3b, are fairly well recognised in the literature as moving westwards from the Eastern Mediterrean/Near Eastern region via the north Mediterranean coast during the Neolithic and later (Scozzari, et al., 2001 ; Richards, 2003 ; Semino et al., 2004 ; Di Giacomo et al., 2004 ; Cruciani et al., 2004, 2007), with sub-groups of both haplogroups expanding again and spreading westwards from the Balkans in the Northern Mediterranean in the Early Bronze Age (Cruciani et al., 2007)."

"The Y-haplogroup J has been argued to be a marker for the movement of Neolithic farmers into Europe (largely as J2) from the near East, spreading a dense swathe across the northern Mediterranean from the Levant through Greece, the Balkans and Albania, and Italy, where J2 accounts for up to 30 % of Y-lineages, to Iberia (Richards 2003, Semino 2004 & see fig 5.8b in Oppenheimer, 2006/7)."

"In other words J2e-M12 (J2b in YCC, 2008) originated and expanded locally from the Balkans to Italy, France and Iberia in south-western Europe during the Early Bronze Age, (see also Di Giacomo et al., 2004, and data in Semino et al., 2004, 2007, Scozzari et al., 2001.). Seen in the context of a hypothetical secondary Indo-European language spread, this Late Chalcolithic Bronze Age expansion scenario could even be consistent with the anomalous finding of significant frequencies (1 %-8 %) of J2e-M12 among Indic (Indo-European) speaking populations of South Asia (table 2, Semino et al., 2004)."

"In the British dataset I examined, nearly all of J belonged to the J2 sub-group ; further, all the STR marker profiles of J2 were most consistent with the J2e-M12 subgroup (as inferred using both STR table 3 of SOM in Cruciani et al 2007 and Appendix table in Di Giacomo et al. 2004), thus implying a Balkan Bronze Age source for much of J2 in Britain. J2 is found throughout Britain mainly concentrating in southern England and in central Scotland in a formerly Pictish region. In both regions it is present at rates from 2 % up to 7 %."

"For each of the three sets of candidate Y-lineages (subgroups of I1b, J2 & E3b1) moving from south-west Europe to Britain and Ireland during the Neolithic and Early Bronze Age, Galicia seems the most likely proximal source, on the multiple lines of evidence discussed above, yet southern France (Narbonne/Keltiké) or Liguria are also possible parallel sources for I1b (as discussed above). However, such indecision could be resolved, if the ultimate single origin of these genetic expansions is taken as the western Balkans. Curiously, this Eastern Mediterranean origin, with an Iberian-staging solution is still consistent with the narrative in the Lebar Gabála Érenn."

"Analysis of Y-chromosomes that could have arrived in the British Isles from the southwest, during the Neolithic and onwards, reveals a limited choice of three main groups of lineages I1b*/I1b2, J2e-M12 and E3b1, which are all found in the same distribution as the three putative western Celtic homelands as well as in the British Isles."

"We can see here that J2b-Alpha has a relatively wide distribution. We also note that J2a-Alpha is the most frequent J2b-cluster in Germany. If we were to speculate about the arrival of J2b-Alpha in the British isles, we might be tempted to suggest either Roman troops of Germanic origin, and/or Anglo-Saxons."

"The last haplogroup, which displayed an overall frequency of more than 5%, consisted of I1-M253 and J2-M172, showing total frequencies of 11.9% and 5.3%, respectively, aligning the Slovenian population with other central European populations (Rootsi et al., 2004). Other lineages observed in the Slovenian population were found at frequencies of less than 5%, with two exceptions related to regional frequency peaks: a frequency peak for haplogroup E1b1b1a1-M78 was detected at 7.3% in Lower Carniola and a frequency peak of 9.1% was detected in Upper Carniola for haplogroup J2-M172."

"In Southern Europe the haplogroup J2, as defined by the M172 marker, can reach frequencies up to 35%, making the dissection of such lineage critical for population studies. Here we present a study on J2 chromosomes from the Italian peninsula. Populations and forensic implications are discussed. A total of 900 individuals were previously genotyped for a number of SNPs, including M172. More than 200 of these have been now genotyped for 7 SNPs within the J2 lineage using a multiplex SNaPshot approach."

"These results support the hypothesis that the surname-chosen Arbereshe are representative of the Y-chromosome genetic variability of the Albanian founder population. Accordingly, the Arbereshe genetic structure can contribute to the interpretation of the recent biological history of the southern Balkans. Intra-haplogroup analyses suggest that this area may have experienced important changes in the last five centuries, resulting in a marked increase in the frequency of haplogroups I2a and J2."

"Taken together, D-M174 and O-M175 account for 71.12% of the paternal lineages in Sherpas, bolstering the case for Tibetans as the ancestral population of Sherpas. Likewise, the relative rarity of other Y haplogroups (<10%) among Sherpas (supplementary Figure S1) were also rare among Tibetans, and mostly absent in other East Asian populations. Most of these haplogroups are prevalent in India (F*-M89, J2b*-M12 and R1a1-M17) and Island Southeast Asia (K*-M9), suggesting either shared ancient Y-chromosome lineages or limited recent admixture of Sherpas with surrounding populations."

"The haplogroup diversity was 0.7794±0.0229 and the most frequent haplogroup was R1b1 followed by I(xI2a2), G, J2 and E1b1a(xE1b1a4,E1b1a7). In the analysis of genetic distance, we observed that the population of Espirito Santo State is closer to European and Latin American populations, being more distant from African and Asian populations, and in the classification of paternal lineages according to their ancestry, there was a greater European contribution (85.88 %), followed by African (11.37 %) and Amerindian (2.75 %), confirming previous studies conducted in the Brazilian population and consistent to the pattern of genetic admixture in Brazil."
