Summary
The D1S8 locus exhibits high polymorphism, generating unique DNA fingerprints for individuals. This makes it a valuable tool for forensic identification and paternity testing in the Hebei Han population.
Area of Science:
- Forensic genetics
- Molecular biology
- Population genetics
Context:
- DNA fingerprinting is crucial for forensic science and paternity testing.
- Understanding genetic variation within populations is essential for accurate identification.
- The D1S8 locus is a target for genetic marker studies.
Purpose:
- To investigate the genetic polymorphism of the D1S8 locus in the Hebei Han population.
- To gather data for establishing a DNA fingerprint database.
- To assess the utility of the D1S8 locus in forensic applications.
Summary:
- Minisatellite variant repeat-polymerase chain reaction (MVR-PCR) was employed on 240 unrelated individuals.
- High levels of polymorphism were observed, with unique digital codes generated for each individual.
- The D1S8 locus demonstrated significant heterozygosity (0.9837) and high polymorphism information content (0.9833).
Impact:
- The D1S8 locus is confirmed as a highly polymorphic marker.
- The findings support the use of D1S8 for reliable forensic identification.
- This research provides foundational data for DNA database construction and paternity testing.
