Identifying DNA markers such as Short Tandem Repeats (STR) can be used to investigate genetic diversity based on levels of heterozygosity within and between populations. Allele frequencies and forensic data for STRs were obtained from a sample of 384 unrelated individuals living in Bahia, Northeastern Brazil. Thus, the present study aimed to identify the allele frequency distribution, in addition to the forensic and genetic data, of 25 STR loci in the population of Bahia.

Located in the Northeast Region, the Pernambuco State is one of the 27 federative units of Brazil. Here, we determined populational data for 23 short tandem repeat (STR) markers - CSF1PO, FGA, TH01, TPOX, vWA, D1S1656, D2S1338, D2S441, D3S1358, D5S818, D7S820, D8S1179, D10S1248, D12S391, D13S317, D16S539, D18S51, D19S433, D21S11, D22S1045, PENTA D, PENTA E and SE33 - of the Pernambuco population. The sample consisted of 767 healthy, adult, unrelated individuals (437 males, 330 females) born and resident in the State of Pernambuco.

Article Synopsis
- * A study analyzed 786 DNA samples from diverse population groups, using advanced sequencing and bioinformatics tools to compare STR variations and calculate frequencies, revealing significant allelic diversity, especially at certain loci.
- * The findings indicate that detailed sequence analysis of STR alleles can significantly improve the statistical approaches used in forensic casework by showcasing how genetic diversity varies among different populations.

In this study, Guangdong Han population was analyzed with Goldeneye™ DNA ID 22NC Kit containing 20 non-CODIS STR loci and a CODIS STR locus. In 503 unrelated individuals, a total of 232 alleles and 813 genotypes were observed. The values of polymorphism information content (PIC), expected heterozygosity (He), and observed heterozygosity (Ho) ranged from 0.

Egypt is a transcontinental country containing substantial ethnic, cultural, and linguistic diversity among its people. This study was conducted to investigate the genetic variation at 15 AmpFlSTR Identifiler short tandem repeat (STR) loci, D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818, and FGA, within and between seven Egyptian populations. Samples of 814 unrelated individuals from Northern Coast, Delta, Greater Cairo, Canal governorates, Northern Upper Egypt, Southern Upper Egypt, and Sinai were investigated.
