“…After grouping at lower level of resolution, haplotype variability values compared to those observed in a Central Italy sample from the other side of Apennine mountains [6] and in an Austrian population sample [7] were very similar ( Table 6). Table 3 Frequency of haplogroups in the two population samples (a) and in the overall Romagna sample (b) In spite of the different historical records and geographic locations, the population samples of Rimini and Valmarecchia showed high genetic affinities likely due to modern demographic migrations that might have eroded the past genetic substructure.…”

“…Although there are data suggesting that locus DYS458 may be affected by a higher mutation rate compared to other tetrameric Y-STR loci [25], the observed microvariants seem to reflect a single mutational event. They all shared a unique Y-SNP background and according to sequencing results a common repeat sequence structure [GAAA] 16 [21,26]. Further collection of joint Y-SNP and Y-STR population data will help to better understand the meaning of this association in terms of human evolutionary history.…”

Analysis of Y-chromosomal SNP haplogroups and STR haplotypes in an Algerian population sample

The distribution of Y-chromosomal single nucleotide polymorphism (SNP) haplogroups and short tandem repeat (STR) haplotypes was determined in a sample of 102 unrelated men of Arab origin from northwestern Algeria (Oran area). A total of nine different haplogroups were identified by a panel of 22 binary markers. The most common haplogroups observed in the Algerian population were E3b2 (45.1%) and J1 (22.5%). Y-STR typing by a 17-loci multiplex system allowed 93 haplotypes to be defined (88 were unique). Striking differences in the allele distribution and gene diversity of Y-STR markers between haplogroups could be found. In particular, intermediate alleles at locus DYS458 specifically characterized the haplotypes of individuals carrying haplogroup J1. All the intermediate alleles shared a common repeat sequence structure, supporting the hypothesis that the variant originated from a single mutational event.

“…[1][2][3] Comparative data from Turkey (490 samples), Italy (162 samples), and the Balkans (399 samples) were obtained from published sources. [18][19][20] All participants recruited and genotyped by our team had at least three generations of paternal ancestry in their country of birth and provided details of their geographical origin and written consent for this study, which was approved by the IRB of the Lebanese American University.…”

Influences of history, geography, and religion on genetic structure: the Maronites in Lebanon

The Genographic Consortium 9Cultural expansions, including of religions, frequently leave genetic traces of differentiation and in-migration. These expansions may be driven by complex doctrinal differentiation, together with major population migrations and gene flow. The aim of this study was to explore the genetic signature of the establishment of religious communities in a region where some of the most influential religions originated, using the Y chromosome as an informative male-lineage marker. A total of 3139 samples were analyzed, including 647 Lebanese and Iranian samples newly genotyped for 28 binary markers and 19 short tandem repeats on the non-recombinant segment of the Y chromosome. Genetic organization was identified by geography and religion across Lebanon in the context of surrounding populations important in the expansions of the major sects of Lebanon, including Italy, Turkey, the Balkans, Syria, and Iran by employing principal component analysis, multidimensional scaling, and AMOVA. Timing of population differentiations was estimated using BATWING, in comparison with dates of historical religious events to determine if these differentiations could be caused by religious conversion, or rather, whether religious conversion was facilitated within already differentiated populations. Our analysis shows that the great religions in Lebanon were adopted within already distinguishable communities. Once religious affiliations were established, subsequent genetic signatures of the older differentiations were reinforced. Post-establishment differentiations are most plausibly explained by migrations of peoples seeking refuge to avoid the turmoil of major historical events.
