In the present study, genetic diversity indices and forensic parameters of Rajput population of Himachal Pradesh, India, were obtained at 20 autosomal short tandem repeat (STR) loci included in the PowerPlex® 21 System (Promega, USA). With 227 alleles and 11.35 ± 0.89 alleles per locus, none of the locus deviated from the Hardy–Weinberg equilibrium (HWE). The most polymorphic and discriminative locus was Penta E. Phylogenetic tree showed high genetic affinity of Rajput population of Himachal Pradesh with Rajputs of Madhya Pradesh and Yadav of Bihar. Overall, the tested 20 autosomal STRs were polymorphic in Rajput population and found suitable in forensic casework and population genetic studies. 相似文献

The distribution of 17 Y-chromosome STR loci DYS456, DYS389I, DYS390, DYS389II, DYS458, DYS19, DYS385a/b, DYS393, DYS391, DYS439, DYS635, DYS392, Y-GATA-H4, DYS437, DYS438, and DYS448 haplotypes was determined in a population sample of 222 unrelated Chinese Han from Shanxi Province, Northern China. A total of 219 haplotypes were observed, and of these, 216 were unique, while 3 were found two times. The overall haplotype diversity was 0.9999 and the discrimination capacity was 0.9865, indicating a high potential for differentiating between male individuals in this population. Comparison analysis via Analysis of Molecular Variance (AMOVA) and construction of MDS plot revealed that Shanxi Han sample clusters with Chinese origin populations and stands far apart of the non-Chinese populations, justifying the establishment of local databases in Shanxi Han population for any future forensic and genetic epidemiology efforts in this region. 相似文献

To investigate the genetic polymorphisms of 59 Y-chromosomal short tandem repeat (Y-STR) loci in the Yulin Han population, 229 unrelated healthy male individuals were analyzed using AGCU Y37 kit and AGCU Y-SUPP Plus kit. A total of 227 different haplotypes were obtained at the 59 Y-STR loci. Among them, 225 haplotypes were unique and 2 haplotypes occurred twice. The overall haplotypic diversity and discrimination capacity were 0.9999 and 0.9913, respectively. The phylogenetic relationships between the studied Yulin Han population and 17 previously reported reference populations were evaluated via multidimensional scaling and Neighbor-Joining analyses based on the haplotypic frequencies of ‘YHRD Maximal Loci’. Phylogenetic analysis revealed that Yulin Han population was closely related to Chinese Han and Hunan Yao populations. These results demonstrated that the 59 Y-STR loci were useful for forensic applications and population genetic studies. 相似文献

Keeping in view the diverse demography of India, present study was undertaken to explore the molecular characterization and forensic relevance of 20 autosomal STRs for the highly diverse population of north Indian state Himachal Pradesh. 724 unrelated individuals from the admixed population of Himachal Pradesh were undertaken for present study and 20 autosomal STRs used to explore genomic diversity of studied population. A total of 270 different alleles along with 13.5 alleles per locus were observed. The allele 8 of the locus TPOX was observed as the most frequent allele. Observed heterozygosity ranged from 0.677 to 0.898, which supported wide range of selection of the unrelated individuals for this study. Combined power of discrimination, power of exclusion, matching probability and paternity index were observed as 1, 0.9999999958, 3.9 × 10−26 and 2.3 × 108 respectively, across the studied loci. In the population differentiation test, studied population showed genetic relatedness with Indian population rather than the populations of West, North and North east countries. Present study deciphered the novel autosomal STR data, which could be useful for the forensic application and population genetic studies. 相似文献

Non autochthonous population is the most numerous group in the Basque Country. This group is named "Residents" to distinguish them from the "Autochthonous Basque" population. In this work, the 17 Y-STR loci distribution of Resident population was studied in a sample of 197 individuals, who were concretely genotyped for DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS439, DYS438, DYS437, DYS448, DYS456, DYS458, DYS635 and Y GATA H4. Resident population showed a high haplotype diversity and discrimination capacity. The distribution of Y-STRs haplotypes of the Resident population was statistically significant different to the one of the Autochthonous Basque population. The genetic substructure found between Resident and Autochthonous Basque 17 Y-STR haplotype distributions advises for the use of two different databases in the Basque Country, to ensure the most trustworthy frequency estimate in casework. 相似文献

Allele frequencies of the 15 autosomal short tandem repeat (STR) loci D8S1179, D21S11, D7S820, CSF1PO D19S433, vWA, TPOX, D18S51, D3S1358, THO1, D13S317, D16S539, D2S1338, D5S818 and FGA were determined in Afridi Pathan population of Uttar Pradesh, India. All the 15 STR loci studied were found to be highly polymorphic with respect to observed heterozygosity values. Adherence to the expectations of the Hardy–Weinberg equilibrium (HWE) was confirmed for all the loci with an exception of TPOX and FGA. The allele 12 in CSF1PO was found to be most frequent. The power of discrimination was found to be high ranging from a minimum of 0.858 for the locus CSFIPO to maximum of 0.962 for the locus FGA, thereby facilitating the validation and efficiency of these STR markers in human identification. Population differentiation test between the studied and neighboring populations revealed significant differences at several loci suggesting the endogamous nature of the studied population. To the best of our knowledge, Afridi Pathan population has not been explored genetically for generating forensic data on STR markers. Therefore, STR allele frequency data of this unique population is a valuable contribution to the existing DNA database on Indian populations. 相似文献

Seventeen Y-chromosomal short tandem repeats (YSTRs)-DYS19, DYS389I, DYS389II, DYS385a/b, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635, and Y-GATA-H4-were analyzed in 252 unrelated male individuals from Botswana. A total of 238 unique haplotypes were identified. The discrimination capacity (DC) was 0.9444 whereas the haplotype diversity (HD) was 0.9990. A database search of the 238 unique haplotypes in the Y chromosome haplogroup database (YHRD) yielded three African American, six Sub-Saharan African, and two admixed South American matches. Five additional African–American matches were detected in the Applied Biosystems Y-STR database. RST, multi-dimensional scaling (MDS) and AMOVA were used to investigate population differentiation in Sub-Saharan Africa and in Botswana. The populations in Sub-Saharan Africa were found to be heterogeneous, with Botswana showing significant differences from its neighbors. No geographic regional or ethnic differentiation was observed within Botswana. Regional and ethnic variation can be useful in forensic working hypotheses. 相似文献

In order to create an autosomal STR loci population database for Himachal Pradesh, 259 blood samples were taken from people residing in various regions of the state and AmpFlSTR® Identifiler® Plus PCR amplification kit was used for evaluation of 15 autosomal STR markers. A total of 149 alleles were investigated in this study with a mean allele number of 9.933 per locus. The locus D2S1338 was most informative in our data, as it had the highest discrimination power (PD-0.967) and the highest polymorphic information content (PIC-0.86). The matching probability and typical paternity index for all the studied loci were observed as 2.9x10-18 and 4.7x105, respectively. Discrimination power (CPD) and exclusion power (CPE) for all the studied loci were observed as 1 and 0.999998. 相似文献
