Aim:To estimate population parameters based on allele frequencies obtained for 15 polymorphic autosomal STR loci investigated in caste and tribal populations of central India (n = 419). Methods:Multiplexed PCR amplifications of the 15 Autosomal STR Loci were performed and amplified products were genotyped using multi-capillary electrophoresis on an ABI 3100 genetic analyser. Parameters of population genetics and forensic interest based on the allele frequencies were calculated. Genetic affinity of the studied populations among themselves and with previously reported populations of India was also analysed using distance-based NJ tree and using PCA plot. Results:All the 15 STR loci were highly informative and discriminating, with CPD of 0.999 99. Except for Brahmins and Rajput, all other studied populations were in Hardy–Weinberg equilibrium (HWE). The only tribe (Gond) population studied showed significant variation with the other four caste populations (Brahmin, Yadav, Rajput and Muslim) studied and formed a cluster with other previously reported tribal populations of India. Nei’s genetic distance based clustering pattern of the NJ tree and the PCA plot showed the same pattern of genetic relationship, i.e. caste and tribal populations formed a distinct cluster. Conclusions:With respect to the distribution of alleles at each STR locus, the studied loci were found to be substantially polymorphic in all the studied populations, indicating good informativeness of all 15 STR markers. The population data generated in this study are useful for forensic, anthropological and demographic studies. [ABSTRACT FROM PUBLISHER]

Aims: Seventeen Y-STR loci (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385a/b, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 and Y-GATA-H4) were analysed in 173 males belonging to the central Indian population with the aim of studying genetic diversity and adding to the population database. Methods: Multiplexed PCR amplifications of the 17 Y STR loci were performed using AmpFlSTR® Yfiler® Kit. Amplified products were genotyped using a multi capillary electrophoresis with POP-4 polymer in ABI Prism 3100 Genetic Analyzer. Population genetic diversity and allele frequencies were calculated. The haplotype data obtained in the study was compared with the Y-STR haplotypes reference database (YHRD,http://www.yhrd.org) and with previously published population data using the AMOVA tool and visualised in two-dimensional multidimensional scaling (MDS) plots. Results: A total of 147 haplotypes were observed, out of which 125 were unique. Haplotype diversity and discriminating capacity were found to be 0.9979 and 0.8497, respectively. The gene diversity at the loci ranged from 0.398–0.785. Genotype diversity at the locus DYS385a/b was found to be 0.869. Conclusions: The population of central India was found to be significantly different (p < 0.05) when compared with populations from other parts of the Indian sub-continent and the population data of other countries. The population data generated in this study are useful for forensic, anthropological and demographic studies. [ABSTRACT FROM AUTHOR]

Aims: Genotypic polymorphism studies at 15 highly polymorphic short tandem repeat (STR) loci were carried out in Bhil tribal population of Madhya Pradesh, in central region of India. Methods: The analysis of 15 autosomal STR loci (TH01, D3S1358, vWA, D21S11, TPOX, D7S820, D19S433, D5S818, D2S1338, D16S539, CSF1PO, D13S317, FGA, D18S51, D8S1179) was done in 183 unrelated individuals of the Bhil tribe. Results: Heterozygosity among the studied 15 autosomal STR loci ranged from 63.5–86.5%. The loci D2S1338 and FGA were found to be mostly polymorphic. All loci fall under Hardy–Weinberg equilibrium, except loci D18S51 and D7S820. These STR loci were highly informative and discriminating, with CPD > 0.99999. Conclusion: The clustering pattern of the NJ tree and the PCA plot showed grouping of the Bhil population with previously reported tribes of central India. [ABSTRACT FROM PUBLISHER]
