Abstract
Complete mitochondrial genomics is an effective tool for studying the demographic history of human populations, but there is still a deficit of mitogenomic data in European populations. In this paper, we present results of study of variability of 80 complete mitochondrial genomes in two Hungarian populations from eastern part of Hungary (Szeged and Debrecen areas). The genetic diversity of Hungarian mitogenomes is remarkably high, reaching 99.9% in a combined sample. According to the analysis of molecular variance (AMOVA), European populations showed a low, but statistically significant level of between-population differentiation (Fst = 0.61%, p = 0), and two Hungarian populations demonstrate lack of between-population differences. Phylogeographic analysis allowed us to identify 71 different mtDNA sub-clades in Hungarians, sixteen of which are novel. Analysis of ancestry-informative mtDNA sub-clades revealed a complex genetic structure associated with the genetic impact of populations from different parts of Eurasia, though the contribution from European populations is the most pronounced. At least 8% of ancestry-informative haplotypes found in Hungarians demonstrate similarity with East and West Slavic populations (sub-clades H1c23a, H2a1c1, J2b1a6, T2b25a1, U4a2e, K1c1j, and I1a1c), while the influence of Siberian populations is not so noticeable (sub-clades A12a, C4a1a, and probably U4b1a4).

Abstract
BACKGROUND Available mitochondrial (mtDNA) data demonstrate genetic differentiation among South Slavs inhabiting the Balkan Peninsula. However, their resolution is insufficient to elucidate the female-specific aspects of the genetic history of South Slavs, including the genetic impact of various migrations which were rather common within the Balkans, a region having a turbulent demographic history. AIM The aim was to thoroughly study complete mitogenomes of Serbians, a population linking westward and eastward South Slavs. SUBJECTS AND METHODS Forty-six predominantly Serbian super-haplogroup U complete mitogenomes were analysed phylogenetically against ∼4000 available complete mtDNAs of modern and ancient Western Eurasians. RESULTS Serbians share a number of U mtDNA lineages with Southern, Eastern-Central and North-Western Europeans. Putative Balkan-specific lineages (e.g. U1a1c2, U4c1b1, U5b3j, K1a4l and K1a13a1) and lineages shared among Serbians (South Slavs) and West and East Slavs were detected (e.g. U2e1b1, U2e2a1d, U4a2a, U4a2c, U4a2g1, U4d2b and U5b1a1). CONCLUSION The exceptional diversity of maternal lineages found in Serbians may be associated with the genetic impact of both autochthonous pre-Slavic Balkan populations whose mtDNA gene pool was affected by migrations of various populations over time (e.g. Bronze Age pastoralists) and Slavic and Germanic newcomers in the early Middle Ages.

Abstract
As microsatellites located on Y chromosome mutate with different rates, they may be exploited in evolutionary studies, genealogical testing of a variety of populations and even, as proven recently, aid individual identification. Currently available commercial Y-STR kits encompass mostly low to moderately mutating loci, making them a perfect choice for the first two applications. Some attempts have been made so far to utilize Y-STRs to provide a discriminatory tool for forensic purposes. Although all 13 rapidly mutating Y-STRs were already multiplexed, no single assay based on single-copy markers allowing at least a portion of close male relatives to be differentiated from one another is available. To fill in the blanks, we constructed and validated an assay comprised of single-copy Y-STR markers only with a mutation rate ranging from 8×10(-3) to 1×10(-2). Performance of the resulting combination of nine RM Y-STRs and four moderately mutating ones was tested on 361 father-son pairs and 1326 males from 9 populations revealing an overall mutation rate of 1.607×10(-1) for the assay as a whole. Application of the proposed 13 Y-STR set to differentiation of haplotypes present among homogenous population of Buryats resulted in a threefold increase of discrimination as compared with 10 Y-STRs from the PowerPlex(®) Y.

Abstract
Background Although the genetic heritage of aboriginal Siberians is mostly of eastern Asian ancestry, a substantial western Eurasian component is observed in the majority of northern Asian populations. Traces of at least two migrations into southern Siberia, one from eastern Europe and the other from western Asia/the Caucasus have been detected previously in mitochondrial gene pools of modern Siberians. Results We report here 166 new complete mitochondrial DNA (mtDNA) sequences that allow us to expand and re-analyze the available data sets of western Eurasian lineages found in northern Asian populations, define the phylogenetic status of Siberian-specific subclades and search for links between mtDNA haplotypes/subclades and events of human migrations. From a survey of 158 western Eurasian mtDNA genomes found in Siberia we estimate that nearly 40% of them most likely have western Asian and another 29% European ancestry. It is striking that 65 of northern Asian mitogenomes, i.e. ~41%, fall into 19 branches and subclades which can be considered as Siberian-specific being found so far only in Siberian populations. From the coalescence analysis it is evident that the sequence divergence of Siberian-specific subclades was relatively small, corresponding to only 0.6-9.5 kya (using the complete mtDNA rate) and 1–6 kya (coding region rate). Conclusions The phylogeographic analysis implies that the western Eurasian founders, giving rise to Siberian specific subclades, may trace their ancestry only to the early and mid-Holocene, though some of genetic lineages may trace their ancestry back to the end of Last Glacial Maximum (LGM). We have not found the modern northern Asians to have western Eurasian genetic components of sufficient antiquity to indicate traces of pre-LGM expansions.

Abstract
In this study we present two forensic cases where mitochondrial DNA HVS I and HVS II haplotypes of evidentiary hairs match reference samples. Based on the information retrieved from mtDNA coding region of reference material, we selected single nucleotide polymorphisms (SNPs) located outside the HVS I and HVS II regions that could increase the informativeness of mtDNA analysis. The SNPs were typed via SNaPshot or dideoxy sequencing technology. In both cases the SNP results allowed for unambiguous exlusion of the evidence and for determining that reference samples originated from the same person.

Abstract
With the aim of uncovering all of the most basal variation in the northern Asian mitochondrial DNA (mtDNA) haplogroups, we have analyzed mtDNA control region and coding region sequence variation in 98 Altaian Kazakhs from southern Siberia and 149 Barghuts from Inner Mongolia, China. Both populations exhibit the prevalence of eastern Eurasian lineages accounting for 91.9% in Barghuts and 60.2% in Altaian Kazakhs. The strong affinity of Altaian Kazakhs and populations of northern and central Asia has been revealed, reflecting both influences of central Asian inhabitants and essential genetic interaction with the Altai region indigenous populations. Statistical analyses data demonstrate a close positioning of all Mongolic-speaking populations (Mongolians, Buryats, Khamnigans, Kalmyks as well as Barghuts studied here) and Turkic-speaking Sojots, thus suggesting their origin from a common maternal ancestral gene pool. In order to achieve a thorough coverage of DNA lineages revealed in the northern Asian matrilineal gene pool, we have completely sequenced the mtDNA of 55 samples representing haplogroups R11b, B4, B5, F2, M9, M10, M11, M13, N9a and R9c1, which were pinpointed from a massive collection (over 5000 individuals) of northern and eastern Asian, as well as European control region mtDNA sequences. Applying the newly updated mtDNA tree to the previously reported northern Asian and eastern Asian mtDNA data sets has resolved the status of the poorly classified mtDNA types and allowed us to obtain the coalescence age estimates of the nodes of interest using different calibrated rates. Our findings confirm our previous conclusion that northern Asian maternal gene pool consists of predominantly post-LGM components of eastern Asian ancestry, though some genetic lineages may have a pre-LGM/LGM origin.

Abstract
Mitochondria's role in crucial metabolic pathways is probably the first answer which comes to our minds for the question: what do these tiny organelles serve for? However, specific features of their DNA made them extremely useful also in the field of anthropology and forensics. MtDNA analyses became a milestone in the complex task of unraveling earliest human migrations. Evidence provided by these experiments left no doubts on modern humans origins pointing to Africa being our cradle. It also contributed to interpretation of putative ways of our dispersal around Asia and Americas thousands years ago. On the other hand, analysis of mtDNA is well established and valuable tool in forensic genetics. When other definitely more popular markers give no answer on identity, it is the time to employ information carried by mitochondria. This chapter summarizes not only current reports on the role of mitochondria in forensics and reconstruction of modern humans phylogeny, but also calls one's attention to a broad range of difficulties and constraints associated with mtDNA analyses.

Abstract
More than a half of the northern Asian pool of human mitochondrial DNA (mtDNA) is fragmented into a number of subclades of haplogroups C and D, two of the most frequent haplogroups throughout northern, eastern, central Asia and America. While there has been considerable recent progress in studying mitochondrial variation in eastern Asia and America at the complete genome resolution, little comparable data is available for regions such as southern Siberia--the area where most of northern Asian haplogroups, including C and D, likely diversified. This gap in our knowledge causes a serious barrier for progress in understanding the demographic pre-history of northern Eurasia in general. Here we describe the phylogeography of haplogroups C and D in the populations of northern and eastern Asia. We have analyzed 770 samples from haplogroups C and D (174 and 596, respectively) at high resolution, including 182 novel complete mtDNA sequences representing haplogroups C and D (83 and 99, respectively). The present-day variation of haplogroups C and D suggests that these mtDNA clades expanded before the Last Glacial Maximum (LGM), with their oldest lineages being present in the eastern Asia. Unlike in eastern Asia, most of the northern Asian variants of haplogroups C and D began the expansion after the LGM, thus pointing to post-glacial re-colonization of northern Asia. Our results show that both haplogroups were involved in migrations, from eastern Asia and southern Siberia to eastern and northeastern Europe, likely during the middle Holocene.

Abstract
It is generally accepted that the most ancient European mitochondrial haplogroup, U5, has evolved essentially in Europe. To resolve the phylogeny of this haplogroup, we completely sequenced 113 mitochondrial genomes (79 U5a and 34 U5b) of central and eastern Europeans (Czechs, Slovaks, Poles, Russians and Belorussians), and reconstructed a detailed phylogenetic tree, that incorporates previously published data. Molecular dating suggests that the coalescence time estimate for the U5 is ∼25–30 thousand years (ky), and ∼16–20 and ∼20–24 ky for its subhaplogroups U5a and U5b, respectively. Phylogeographic analysis reveals that expansions of U5 subclusters started earlier in central and southern Europe, than in eastern Europe. In addition, during the Last Glacial Maximum central Europe (probably, the Carpathian Basin) apparently represented the area of intermingling between human flows from refugial zones in the Balkans, the Mediterranean coastline and the Pyrenees. Age estimations amounting for many U5 subclusters in eastern Europeans to ∼15 ky ago and less are consistent with the view that during the Ice Age eastern Europe was an inhospitable place for modern humans.

Abstract
The essence of anthropological typology is to classify people as belonging to anthropological types according to predetermined sets of morphological traits. The authors of the concept claim that traits characteristic of a given type are monogenic and have a Mendelian inheritance pattern. According to these assumptions, it is possible to unambiguously determine hair or eye color, etc. on the basis of scull characteristics only. Such a solution could be of a great importance in identification based on the skeleton but for the fact that the concept contradicts the current body of knowledge of population genetics or evolutionary biology analyses. It is widely known that the vast majority of morphological traits is determined by a complex of cooperating genes. Moreover, it has been demonstrated that genetic distances between populations are low, while most of the diversity is attributed to intrapopulation variation. Therefore, rejecting the classic concept of race seems to be justified. For this reason, today it is more reasonable to use the panel of SNP markers (AIMs) in identification of unknown individuals while aiming at prediction of their ethnic ancestry rather than to believe in the scientific value of anthropological typology.

Abstract
In the last few years, one could observe an increased interest in mitochondrial DNA (mtDNA) single nucleotide polymorphisms (SNPs) as a result of their numerous applications in population genetics and forensic science. Continuous progress in molecular technologies together with an increasing body of phylogenetic knowledge, based mainly on complete mitochondrial genome sequencing, allows both for selection and accurate typing of many SNPs in mitochondrial DNA. Among the SNP typing techniques, due to its high sensitivity and promptness of determinations, minisequencing appears to be one of the fastest and most frequently applied methods in forensic laboratories. This review presents currently available minisequencing systems used for haplogroup assignment of mtDNA in European, East Asian and Native American populations.
