Human Neutral Genetic Variation and Forensic STR Data
The forensic genetics field is generating extensive population data on polymorphism of short tandem repeats (STR) markers in globally distributed samples. In this study we explored and quantified the informative power of these datasets to address issues related to human evolution and diversity, by using two online resources: an allele frequency dataset representing 141 populations summing up to...
متن کاملThe landscape of human STR variation.
Short tandem repeats are among the most polymorphic loci in the human genome. These loci play a role in the etiology of a range of genetic diseases and have been frequently utilized in forensics, population genetics, and genetic genealogy. Despite this plethora of applications, little is known about the variation of most STRs in the human population. Here, we report the largest-scale analysis o...
متن کاملGenetic Variation of Informative Short Tandem Repeat (STR) Loci in an Iranian Population
In the present study, genotyping of six short tandem repeat (STR) loci including CSF1PO, D16S539, F13A01, F13B, LPL and HPRTB was performed on genomic DNA from 127 unrelated individuals from the Iranian province of Isfahan. The results indicated that the allele and genotype distributions were in accordance with Hardy-Weinberg expectations. The observed heterozygosity (Ho), expected heterozygosi...
متن کاملY Chromosome STR Analysis in Forensic Practice
Currently, the gradual introduction and routine application of validated Y chromosomal STR systems in stain analysis is being experienced. These systems are powerful forensic tools especially for the area of sexual assault evidence and are superior to autosomal systems for two reasons: the differential cell lysis step prior to the PCR is replaced by a sex chromosome selection during PCR and the...
متن کاملStatistics of selectively neutral genetic variation.
Random models of evolution are instrumental in extracting rates of microscopic evolutionary mechanisms from empirical observations on genetic variation in genome sequences. In this context it is necessary to know the statistical properties of empirical observables (such as the local homozygosity, for instance). Previous work relies on numerical results or assumes Gaussian approximations for the...
