Genetic studies on Bosniaks

As with all modern European nations, a large degree of 'biological continuity' exists between the Bosniaks and their ancient predecessors with Bosniak Y chromosomal lineages testifying to predominantly Paleolithic European ancestry.[1][2] A majority (>67%) of Bosniaks belong to one of the three major European Y-DNA haplogroups: I2 (43.50%), R1a (15.3%) and R1b (3.5%), while a minority belongs to less frequently occurring haplogroups E-V13 (12.90%) and J2 (8.7%), along with other more rare lineages.[3]

Studies based on bi-allelic markers of the NRY (non-recombining region of the Y-chromosome) have shown the three main ethnic groups of Bosnia and Herzegovina (Bosniaks, Bosnian Serbs and Bosnian Croats) to share, in spite of some quantitative differences, a large fraction of the same ancient gene pool distinct for the region.[4] Analysis of autosomal STRs have moreover revealed no significant difference between the population of Bosnia and Herzegovina and neighbouring populations.[5]

Autosomal DNA of Bosniaks in Bosnia and Herzegovina[edit]

Genetic structure of Bosnians within European context according to three genetic systems: Autosomal DNA (A), Y-DNA (B) and mtDNA (C) per Kushniarevich et al. (2015)

An autosomal analysis study of 90 samples showed that Western Balkan populations had a genetic uniformity, intermediate between South Europe and Eastern Europe, in line with their geographic location. According to the same study, Bosnians (together with Croatians) are by autosomal DNA closest to East European populations and overlap mostly with Hungarians.[6] In the 2015 analysis, Bosnians formed a western South Slavic cluster with the Croatians and Slovenians in comparison to eastern cluster formed by Macedonians and Bulgarians with Serbians in the middle. The western cluster (Bosnians included) has an inclination toward Hungarians, Czechs, and Slovaks, while the eastern cluster toward Romanians and some extent Greeks.[7] Based on analysis of IBD sharing, Middle Eastern populations most likely did not contribute to genetics in Islamicized populations in the Western Balkans, including Bosniaks, as these share similar patterns with neighboring Christian populations.[6]

Y-DNA frequency of Bosniaks in Bosnia and Herzegovina[edit]

Y-DNA studies on Bosniaks (in Bosnia and Herzegovina) show close affinity to other neighboring South Slavs.[8] Y-DNA results show notable frequencies of I2 with 43.50% (especially its subclade I2-CTS10228+), R1a with 15.30% (mostly its two subclades R1a-CTS1211+ and R1a-M458+), E-V13 with 12.90% and J-M410 with 8.7%. The frequency of haplogroup I2, especially its subclade I2-CTS10228 and its variance, peaks over a large geographic area covering Bosnia and Herzegovina, Croatia, Serbia, Montenegro, Macedonia, Northern Albania, Bulgaria, Romania, Moldova, Slovakia, Ukraine, Belarus and western Russia. In comparison to older research which argued a prehistoric autochthonous origin of the haplogroup I2 in western Balkans,[nb 1] the most recent research by O.M. Utevska (2017) found the haplogroups STR haplotypes have the highest diversity in Ukraine, with ancestral STR marker result "DYS448=20" comprising "Dnieper-Carpathian" cluster, while younger derived result "DYS448=19" comprising the "Balkan cluster" which is predominant among the South Slavs.[14] The clusters divergence and gradual expansion from the Carpathians in the direction of the Balkan peninsula happened approximately 2,860 ± 730 years ago, coinciding with the Slavic migration. The lack of diversity of "DYS448=19" haplotypes in the Western Balkan also indicate a founder effect.[14] Y-DNA studies done for the majority Bosniak populated city of Zenica and Tuzla Canton, shows however a drastic increase of the two major haplogroups I2 and R1a. Haplogroup I2 scores 52.20% in Zenica (Peričić et al., 2005) and 47% in Tuzla Canton (Dogan et al., 2016), while R1a increases up to 24.60% and 23% in respective region.[15][16] Principal component analysis of Y-chromosomal haplogroup frequencies among the three ethnic groups in Bosnia and Herzegovina, Serbs, Croats, and Bosniaks, showed that Bosnian Serbs and Bosniaks are by Y-DNA closer to each other than either of them is to Bosnian Croats.[17]

Mitochondrial DNA[edit]

Genetically, on the maternal X chromosome line, a majority (>75%) of Bosnians belong to three of the eleven major European mtDNA haplogroups - H (47.92%), U (19.44%) and J (6.94%), while a large minority (>25) belongs to other rare mitochondrial lineages.[21] The mtDNA studies shows that the Bosnian population partly share similarities with other Southern European populations (especially with mtDNA haplogroups such as pre-HV (today known as mtDNA haplogroup R0), HV2 and U1), but are for the mostly featured by a huge combination of mtDNA subclusters that indicates a consanguinity with Central and Eastern Europeans, such as modern German, West Slavic, East Slavic and Finno-Ugric populations. There is especially the observed similarity between Bosnian, Russian and Finnish samples (with mtDNA subclusters such as U5b1, Z, H-16354, H-16263, U5b-16192-16311 and U5a-16114A). The huge differentiation between Bosnian and Slovene samples of mtDNA subclusters that are also observed in Central and Eastern Europe, may suggests a broader genetic heterogeneity among the Slavs that settled the Western Balkans during the early Middle ages.[22]

Note[edit]

  1. ^ The SNP I-P37 itself formed approximately 20 thousand YBP and had TMRCA 18 thousand YBP according to YFull,[9] being too old and widespread as an SNP for argumentation of autochthony as well the old research used outdated nomenclature. According to "I-P37 (I2a)" project at Family Tree DNA, the divergence at STR marker DYS448 20 > 19 is reported since 2007,[10] while the SNP which defines the STR Dinaric-South cluster, I-PH908, is reported since 2016.[11] The SNP I-PH908 at ISOGG phylogenetic tree is named as I2a1a2b1a1a1c,[12] while formed and had TMRCA approximately 1,800 YBP according to YFull.[13]
