“…The 15 STR loci were highly polymorphic with a significant proportion (40%) of rare alleles The genetic heterogeneity of North African populations with more or less affinities with Middle East, Europe and Sub-Saharan Africa has been suggested by authors using mtDNA (Plaza et al, 2003;Coudray et al, 2009), Y-chromosome DNA (Arredi et al, 2004;Capelli et al, 2006), STR markers (Capelli et al, 2006;El Ossmani et al, 2010) and SNPs (Botigué et al, 2013;Henn et al, 2012). In some studies, a West-to-East gradient, ranging from West Sahara to the Middle East has been described, which we could not detect in the present study, most studies that have shown that genetic distances are correlated with geographical distances (Ramachandran et al, 2005;Lao et al, 2008) were performed at large geographic scale.…”

Patterns of genetic variation in human populations have been described for decades. However, North Africa has received little attention and Algeria, in particular, is poorly studied, Here we genotyped a Berber-speaking population from Algeria using 15 short tandem repeat (STR) loci D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818 and FGA from the commercially available AmpF/STR Identifiler kit. Altogether 150 unrelated North Algerian individuals were sampled across 10 administrative regions or towns from the Bejaia Wilaya (administrative district). We found that all of the STR loci met Hardy-Weinberg equilibrium expectations, after Bonferroni correction and that the Berber-speaking population of Bejaia presented a high level of observed heterozygosity for the 15 STR system (>0.7). Genetic parameters of forensic interest such as combined power of discrimination (PD) and combined probability of exclusion (PE) showed values higher than 0.999, suggesting that this set of STRs can be used for forensic studies. Our results were also compared to those published for 42 other human populations analyzed with the same set. We found that the Bejaia sample clustered with several North African populations but that some geographically close populations, including the Berber-speaking Mozabite from Algeria were closer to Near-Eastern populations. While we were able to detect some genetic structure among samples, we found that it was not correlated to language (Berber-speaking versus Arab-speaking) or to geography (east versus west). In other words, no significant genetic differences were found between the Berber-speaking and the Arab-speaking populations of North Africa. The genetic closeness of European, North African and Near-Eastern populations suggest that North Africa should be integrated in models aiming at reconstructing the demographic history of Europe. Similarly, the genetic proximity with sub-Saharan Africa is a reminder of the links that connect all African regions.

“…Therefore, they can be usually utilized in the fields of personal identification and paternity testing (Chen et al, ; Guo, ; He, Wang, Liu, Hou, & Wang, ). Additionally, they are also used to uncover the population genetic backdrop and structure (Eaaswarkhanth et al, ; El Ossmani et al, ; Li et al, ; Lowery et al, ; Zhang et al, ). The STR loci are potentially related to the genetic geographic distribution and microevolutionary process of human population, which can reveal the different population genetic structure at the continental and sub‐continental scales (Verrier, Waite, Linney, Sutton, & Galgut, ).…”

BackgroundIt is meaningful to expand the available population information on forensic medicine and to investigate the genetic characteristics of Han population from Jilin Province, Northeast China.MethodsIn this study, we investigated the genetic characteristics of 24 Y‐chromosomal short tandem repeat (STR) loci in 1,088 unrelated Chinese Han male individuals from Jilin Province, using DNATyperTM Y24 amplification kit. Additionally, we performed the population comparison between the Jilin population and the other nine reported populations based on the Y‐STR genotyping haplotypes.ResultsA total of 1,067 different haplotypes were found from 1,088 unrelated individuals, of which 1,046 were unique and 21 were shared by two individuals. The gene diversity values of 22 loci ranged from 0.3870 (DYS391) to 0.9668 (DYS385ab). The random match probability was 0.0010 with the discrimination capacity of 0.9807. Population comparison showed that there were minor differences compared to Beijing Chinese Han, China Manchu, Gansu Chinese Han, and Jiangsu Chinese Han, but major differences with respect to the populations of Guangdong Chinese Han, Yunnan Chinese Han, China Hui, China Korean, and China Tibetan.ConclusionOur results showed that the 24 Y‐STR loci in Jilin Han population are valuable for forensic application and human genetics.

“…To test hypotheses of population origins, autosomal STR data from our sample were compared to geographically assumed-related populations. In this way, data on 13 STRs (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, VWA, TPOX, D18S51, FGA, D5S818, D16S539) in a total of 21 populations, were selected from the available literature and compared to our sample, including populations from North Africa (Moroccan Berber, Tunisian Berber, Tunisian Arabic and Libyan) ( Cherni et al, 2005 , El Ossmani et al, 2010 , Khodjet-el-Kkil et al, 2012 ); Southern Europe (Italy, Spain and Greece) ( Brisighelli et al, 2009 , Camacho et al, 2007 , Kovatsi et al, 2006 ); and Middle East (Palestine, Syria, Lebanon, UAE, Saudi Arabia, Oman, Yemen, Iraq, Kuwait, Egypt and Sudan) ( Abdin et al, 2003 , Abu Halima et al, 2009 , Alenizi et al, 2008 , Alshamali et al, 2005 , Babiker et al, 2011 , Barni et al, 2007 , Chouery et al, 2010 , Omran et al, 2009 ) and Western Asia (Pakistan, Iran, Fars) ( Alshamali et al, 2005 , Hedjazi et al, 2013 , Rakha et al, 2009 ).…”

“…Alternatively, if Morocco is an autochthonous North African population (with no recent gene flow from groups in Middle East or Europe), autosomal STR frequencies will be within the range of other populations in North Africa, and Moroccan will be more genetically similar to other North African groups with a Berber ancestry. Previous studies presenting STR data from the Moroccan population either used small samples that were often collected in urban areas of a single province to study relationships between Morocco and other populations ( Chbel et al, 2003 , El Ossmani et al, 2009 , El Ossmani et al, 2010 ) ( Table 1 ). This study represents one of the most comprehensive samples of Morocco yet analyzed for autosomal STR variation, with 377 male and female throughout the country.…”

Detecting population substructure and ancestry is a critical issue for both association studies of health behaviors and forensic genetics. Determining aspects of a population's genetic history as potential sources of substructure can aid in design of future genetic studies. Within this context, fifteen autosomal short tandem repeat (STR), were used to examine population genetic structure and hypotheses of the origin of the modern Moroccan population from individuals belonging to three different ethnical groups from Morocco (Arab, Berber and Sahrawi), by comparing their autosomal STR variation with that of neighboring and non-neighboring populations in North Africa, Europe and Middle East as well as proposed ancestral populations in Morocco (Berber). We report on the results that the gradient of North African ancestry accounts for previous observations of low levels of sharing with Near East and a substantially increased gene flow especially from Morocco and Spain.
