As the result of the communist terror in Poland, during years 1944-1956 more than 50,000 people died. Their bodies were buried secretly, and most places are still unknown. The research presents the results of identification of people buried in one of many mass graves, which were found at the cemetery Powązki Military in Warsaw, Poland. Exhumation revealed the remains of eight people, among which seven were identified genetically. Well-preserved molars were used for the study. Reference material was collected from the closest living relatives...

Members of the Mongol imperial family (designated the Golden family) are buried in a secret necropolis; therefore, none of their burial grounds have been found. In 2004, we first discovered 5 graves belonging to the Golden family in Tavan Tolgoi, Eastern Mongolia. To define the genealogy of the 5 bodies and the kinship among them, SNP and/or STR profiles of mitochondria, autosomes, and Y chromosomes were analyzed. Four of the 5 bodies were determined to carry the mitochondrial DNA haplogroup D4, while the fifth carried haplogroup CZ, indicating that this individual had no kinship with the others...

Next-generation sequencing (NGS) can produce massively parallel sequencing (MPS) data for many targeted regions with a high depth of coverage, suggesting its successful application to the amplicons of forensic genetic markers. In the present study, we evaluated the practical utility of MPS in Y-chromosome short tandem repeat (Y-STR) analysis using a multiplex polymerase chain reaction (PCR) system. The multiplex PCR system simultaneously amplified 24 Y-chromosomal markers, including the PowerPlex(®) Y23 loci (DYS19, DYS385ab, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS481, DYS533, DYS549, DYS570, DYS576, DYS635, DYS643, and YGATAH4) and the M175 marker with the small-sized amplicons ranging from 85 to 253bp...

Y-chromosomal short tandem repeat (Y-STR) markers are commonly used in forensic genetics. Male-specific haplotypes provided by commercial Y-STR kits allow discriminating between many - but not all - unrelated men, while they mostly fail to separate related ones. Aiming to improve male relative and paternal lineage differentiation, a set of 13 rapidly-mutating (RM) Y-STRs was previously identified and introduced to forensic Y-chromosome analysis. Recently, their value was highlighted by separating 99% of over 12,200 unrelated men from 111 global populations, as well as 29% of over 2500 male relative pairs, the vast majority were father-sons...

Nusa Tenggara, including East Timor, located at the crossroad between Island Southeast Asia, Near Oceania, and Australia, are characterized by a complex cultural structure harbouring speakers from two different major linguistic groups of different geographic origins (Austronesian (AN) and non-Austronesian (NAN)). This provides suitable possibilities to study gene-language relationship; however, previous studies from other parts of Nusa Tenggara reported conflicting evidence about gene-language correlation in this region...

In this study we set out to test at a micro-geographic scale for the potential effects of differences in urbanization degree on Y-chromosomal diversity and the paternal lineage differentiation of "conventional" and rapidly-mutating (RM) Y-STR markers. To avoid systematic underrepresentation of common lineages, 551 male samples were collected under a sampling regime allowing for the inclusion of paternal relatives. All participants came from a small, topographically highly structured, yet culturally homogeneous settlement area in the Tyrolean Alps of Austria, a region that is characterized by a longstanding coexistence of communities differing considerably in size and connection...

Y-chromosomal loci have proven useful in solving investigations where low levels of male DNA are present in a high female DNA background. An intrinsic limitation of Y-STRs compared with autosomal STRs is a reduced power of discrimination due to a lack of recombination throughout most of the Y-chromosome. Thus, in an effort to increase the power of discrimination we have developed a new 6-dye, 27-plex Y-STR system that includes the 17 loci from the Yfiler(®) and Yfiler(®) Direct kits (DYS19, DYS385a/b, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 (Y GATA C4), and Y GATA H4) plus three highly polymorphic Y-STR loci (DYS460, DYS481, and DYS533), and seven rapidly mutating Y-STR loci (DYF387S1a/b, DYS449, DYS518, DYS570, DYS576, DYS627) which allow for improved discrimination of related individuals...

Here we report the results of fine resolution Y chromosomal analyses (Y-SNP and Y-STR) of 267 Bantu-speaking males from three populations located in the southeast region of Africa. In an effort to determine the relative Y chromosomal affinities of these three genotyped populations, the findings are interpreted in the context of 74 geographically and ethnically targeted African reference populations representing four major ethno-linguistic groups (Afro-Asiatic, Niger Kordofanin, Khoisan and Pygmoid). In this investigation, we detected a general similarity in the Y chromosome lineages among the geographically dispersed Bantu-speaking populations suggesting a shared heritage and the shallow time depth of the Bantu Expansion...

Analysis of Y-chromosome haplogroup distribution is widely used when investigating geographical clustering of different populations, which is why it plays an important role in population genetics, human migration patterns and even in forensic investigations. Individual determination of these haplogroups is mostly based on the analysis of single nucleotide polymorphism (SNP) markers located in the non-recombining part of Y-chromosome (NRY). On the other hand, the number of forensic and anthropology studies investigating short tandem repeats on the Y-chromosome (Y-STRs) increases rapidly every year...

OBJECTIVE: A case of half sibling was determined with multiple genetic markers, which could be potentially applied for determination of half sibling relationship from same father. METHODS: Half sibling relationship was detected by 39 autosomal STR genetic markers, 23 Y-chromosomal STR genetic markers and 12 X -chromosomal STR genetic markers among ZHAO -1, ZHAO -2, ZHAO -3, ZHAO -4, and ZHAO-5. RESULTS: According to autosomal STR, Y-STR and X-STR genotyping results, it was determined that ZHAO-4 (alleged half sibling) was unrelated with ZHAO-1 and ZHAO-2; however, ZHAO-3 (alleged half sibling), ZHAO-5 (alleged half sibling) shared same genetic profile with ZHAO-1, and ZHAO-2 from same father...

In some cases of sexual assault the victim may not report the assault for several days after the incident due to various factors. The ability to obtain an autosomal STR profile of the semen donor from a living victim rapidly diminishes as the post-coital interval is extended due to the presence of only a small amount of male DNA amidst an overwhelming amount of female DNA. Previously, we have utilized various technological tools to overcome the limitations of male DNA profiling in extended interval post-coital samples including the use of Y-chromosome STR profiling, cervical sample, and post-PCR purification permitting the recovery of Y-STR profiles of the male DNA from samples collected 5-6 days after intercourse...
