<b>Background and Objective:</b> Indonesia consists of various ethnic groups with diverse cultures. However, research on allele frequencies and genetic variations of each ethnic group in Indonesia has not been well established. Therefore, a study was conducted on 13 STR loci panels to analyze the mentawai population as an enhancement of the Indonesian population's genetic data library and genetic variation. Mentawai is one of the Indonesian tribes who live on Mentawai Island, West Sumatera. <b>Materials and Methods:</b> The PrepFiler kit to extract DNA from blood and the GlobalFiler kit for amplifying the 13 loci were used. The genetic analyzer ABI PRISM 3500 was used to detect PCR products. Data were processed and analyzed by EasyDNA and FORSTAT software. <b>Results:</b> The allele frequency data for 13 autosomal loci in Mentawai populations were obtained. Expected heterozygosity was found with a minimum of 0.607 for TPOX and a maximum of 0.866 for FGA. Power of discrimination (PD) values ranges from TPOX (0.792) to FGA (0.968). Polymorphic information content (PIC) values for all loci were high, ranging from 0.642 for TPOX to 0.921 for vWA. Three off-ladder alleles in these findings were detected. Allele 6.3 at the TH01 loci and allele 14.2 at the D18S51 loci are exquisite. The mean expected heterozygosity and mean power of discrimination value across the 13 loci were 75.9 and 90.1%, indicating striking gene diversity. <b>Conclusion:</b> These 13 STR loci can be used for population genetic studies and forensic identification.

Forensic science takes advantage of population variability in autosomal Short Tandem Repeat (STR) lengths to establish human identification. The most common method for DNA profiling by STR is based on PCR, where the highly polymorphic STR regions are amplified and analysed using Capillary Electrophoresis (CE) or Massively Parallel Sequencing (MPS). MPS determines not only the repeat length, but also the repeat structure and variations in the flanking regions, making this method superior in discriminatory power compared to CE.

DNA mixtures containing semen and vaginal fluid are common biological samples in forensic analysis. However, the analysis of semen-vaginal fluid mixtures remains challenging. In this study, to solve these problems, it is proposed to combine semen-specific CpG sites and closely related microhaplotype sites to form a new composite genetic marker (semen-specific methylation-microhaplotype).

In this study, we developed and validated a novel microhaplotype (MH) panel, the FGID Microhaplotype Kit, which contains 232 loci and was specifically designed for forensic kinship analysis. The performance of the panel was evaluated through rigorous testing that included sensitivity, species specificity, inhibitor resistance, uniformity, stability, accuracy and mixture deconvolution. The results showed that the kit is capable of reliably detecting all loci with minimal DNA input.

Y-chromosomal short tandem repeats (Y-STRs) at rapidly mutating (RM) loci have been suggested as tools for differentiating paternally related males. RMplex is a recently developed system that incorporates 26 RM loci and four fast-mutating (FM) loci, targeting 44 male-specific loci. Here, we evaluated the RMplex by estimating Y-STR mutation rates and the overall differentiation rates for 542 Korean father-son pairs, as well as the genetic population values for 409 unrelated males.

Purpose: The objective of the study was to establish the prevalence of Sarcocystis (Apicomplexa, Sarcocystidae) in brown rats from Jleeb Al-Shuyoukh, Kuwait, and to describe detected parasites using morphological and DNA analysis methods.
Methods: Ninety-eight brown rats (Rattus norvegicus) were examined for Sarcocystis spp. Obtained sarcocysts were investigated using light microscopy and electron microscopy.
