The Fang population of Equatorial Guinea characterised by 15 STR-PCR polymorphisms

Area of Science:

• Population genetics
• Forensic science
• Human genetics

Background:

• Short tandem repeat (STR) loci are crucial markers in forensic genetics.
• Understanding population-specific allele frequencies is essential for accurate forensic identification.
• The Fang population of Bioko Island represents a unique demographic for genetic studies.

Purpose of the Study:

• To determine the allele frequencies of 15 STR loci in the Fang population.
• To assess the forensic genetic utility of these STR loci within this population.
• To evaluate genetic diversity and population structure.

Main Methods:

• Analysis of allele frequencies for 15 specific STR loci (D8S1179, D21S11, D7S820, CSF1PO, D19S433, HUMVWA31A, HUMTPOX, D18S51, D3S1358, HUMTHO1, D13S317, D16S539, D2S1338, D5S818, and HUMFGA).
• Application of population genetics principles to analyze genetic data.
• Statistical analysis to determine Hardy-Weinberg equilibrium and forensic parameters.

Main Results:

• Allele frequencies for all 15 STR loci were successfully determined for the Fang population.
• No deviation from Hardy-Weinberg equilibrium was observed across all analyzed loci.
• Statistical parameters indicated significant forensic utility for the studied STR systems.

Conclusions:

• The analyzed STR loci are genetically informative and suitable for forensic applications in the Fang population.
• The genetic data contributes to the understanding of population structure in Equatorial Guinea.
• This study provides valuable baseline data for forensic investigations involving the Fang population.
