Diversity of nuclear microsatellite markers were analyzed in a reference sample of the population of northeast Bosnia and Herzegovina. 437 samples taken from unrelated individuals were processed and three samples of paternity proof were shown. Detection effectiveness profile of the research, points to a valid choice of method of extraction, amplification and genotyping short tandem repeat (STR) loci with PowerPlextm16 kit. Genetic analysis of allelic variants of the 15 STR loci PowerPlextm16 kit detected 17 samples determined as rare allelic variants or microvariants. Samples were divided into 15 different allelic variants at 7 different loci, and are: in locus D7S820, D16S539, D3S1358, D18S51, PENTA D, PENTA E and in locus vWA. Genetic analysis of mutations in cases of paternity determined three examples of single-step mutations in the loci FGA, Penta D and D3S1358. Genetic analysis of observed STR loci detected three allelic variant of genotype combination 7/10/11.3 in locus D7S820 Type II. Population genetic analysis of STR loci in a representative sample of the population of northeast Bosnia and Herzegovina included the application of the assessment tests of within-population genetic diversity and interpopulation diversity, as well as genetic differentiation between populations: North-eastern Bosnia and Herzegovina (BH) and BH general reference, then the Croatian population, Macedonian, Serbian and Slovenian. Based on the result analysis of specific forensic parameters, it can be assumed that the most informative marker is PENTA E for population genetic analysis and forensic testing in the population of northeast Bosnia and Herzegovina. Research results fit regional STR database of this part of Europe.
MtDNA variations, determined in terms of mtDNA haplogroups, were analyzed, the sample consisted of the human population of Bosnia and Herzegovina from the teritory of the Tuzla region. The analysis included a total of 245 mtDNA samples (kin unrelated individuals). Determination of mtDNA haplogroups was studied by using haplogroup-specific PCR-RFLP markers of a coding region of mtDNA. We observed that 95.11% of investigated individuals in the Tuzla region belong to the Western-Euroasian mtDNA haplogroups: H, V, T, I, J, K, U, X, W. The impact of migratory activities on the population structure of the Tuzla region was estimated by analysis within- and of intergroup genetic differences (index of genetic specificities, pairwise FST analysis and exact-p test) of indigenous and migrant categories (recent, internal, and historical). The analysis showed that a significant demographic influence on the genetic structure of indigenous people was exerted by the category of recent migrants only.

Aim To report on the use of STR, Y-STRs, and miniSTRs typing methods in the identification of victims of revolutionary violence and crimes against humanity committed by the Communist Armed Forces during and after World War II in which bodies were exhumed from mass and individual graves in Slovenia. Methods Bone fragments and teeth were removed from human remains found in several small and closely located hidden mass graves in the Skofja Loka area (Lovrenska Grapa and Žolsce) and 2 individual graves in the Ljubljana area (Podlipoglav), Slovenia. DNA was isolated using the Qiagen DNA extraction procedure optimized for bone and teeth. Some DNA extracts required additional purification, such as N-buthanol treatment. The Quantifiler TM Human DNA Quantifica tion Kit was used for DNA quantification. Initially, PowerPlex 16 kit was used to simultaneously analyze 15 short tandem repeat (STR) loci. The PowerPlex S5 miniSTR kit and AmpFSTR® MiniFiler PCR Amplification Kit was used for additional analysis if preliminary analysis yielded weak partial or no profiles at all. In 2 cases, when the Pow erPlex 16 profiles indicated possible relatedness of the remains with reference samples, but there were insufficient probabilities to call the match to possible male paternal relatives, we resorted to an additional analysis of Y-STR markers. PowerPlex® Y System was used to simultaneously amplify 12 Y-STR loci. Fragment analysis was performed on an ABI PRISM 310 genetic analyzer. Matching probabilities were estimated using the DNA-View software. Results Following the Y-STR analysis, 1 of the “weak matches” previously obtained based on autosomal loci, was confirmed while the other 1 was not. Combined standard STR and miniSTR approach applied to bone samples from 2 individual graves resulted in positive identifications. Finally, using the same approach on 11 bone samples from hidden mass grave Žolosce, we were able to obtain 6 useful DNA profiles. Conclusion The results of this study, in combination with previously obtained results, demonstrate that Y-chromosome testing and mini STR methodology can contribute to the identification of human re mains of victims of revolutionary violence from World War II.
Modern Bosnia and Herzegovina is a multi-ethnic and multi-religion country, with a very stormy history. Certain archaeological findings indicate continuous population of its territory since the Paleolithic. In time, vast number of different factors jointly influenced fascinating diversity of local human populations. A great number of small, more or less isolated, indigenous populations, make this area quite attractive for population-genetic surveys of different levels and approaches. Austro-Hungarian military physicians conducted the very first known bio-anthropological analyses of Bosnia-Herzegovina population at the end of the 19th century. Thus, the first step towards resolving the genetic structures of local B&H human populations was made. The studies that followed (conducted throughout most of the 20th century) were primarily based on the observation of various phenotypic traits. This stage was followed by the examination of various cytogenetic and fundamental DNA based molecular markers. The efforts undertaken over the last three centuries revealed "human genetic treasure" in Bosnia and Herzegovina. However, even now, after all the studies that were conducted, many interesting features remain to be discovered and described within the existing local human populations.
