In the present study, we investigated the genetic polymorphisms of 20 novel STR loci and one previously studied locus in the Xibe ethnic group from China, as well as its genetic relationships with neighboring populations. Totally 226 unrelated healthy Xibe individuals were involved in the study. At least 5 alleles were observed for each locus, with the minimum and maximum allelic frequencies of 0.0022 and 0.5221, respectively. We obtained the lowest and highest observed heterozygosity and expected heterozygosity at locus D1S1627 and D19S433, respectively. The values of combined power of discrimination and probability of exclusion of all the 21 STR loci were 0.99999999999999999997310 and 0.999998650, respectively. Analyses of interpopulation differentiation, principal component analysis, genetic distance and phylogenetic tree revealed the relationships between Xibe group and its neighboring groups, showing that the studied Xibe group had a close genetic relationship with the Mongolian group. The present results indicated that these 21 STR loci had high genetic polymorphisms in the studied Xibe group, and were capable for the paternity testing and individual identification in forensic application.

An exploratory population genetics software environment able to handle large samples of molecular data (RFLPs, DNA sequences, microsatellites), while retaining the capacity of analyzing conventional genetic data (standard multi-locus data or mere allele frequency data). (entry from Genetic Analysis Software)
View all literature mentionsPopulation genetic data analysis software package. Used to perform exact Hardy Weinberg Equilibrium test. Used for population differentiation and for genotypic disequilibrium among pairs of loci. Computes estimates of F-statistics, null allele frequencies, allele size-based statistics for microsatellites, etc. and performs analyses of isolation by distance from pairwise comparisons of individuals or population samples.
View all literature mentionsGenotyping software package that provides DNA sizing and quality allele calls for all Applied Biosystems electrophoresis-based genotyping systems. GeneMapper specializes in multiapplication functionality, including amplified fragment length polymorphism, loss of heterozygosity, microsatellite, and SNP genotyping analysis. The software provides remote auto-analysis and command line operation, and allows for multiuser, client-server deployment.
