Forensic scientists analyzed the D6S366 short tandem repeat (STR) locus in 200 individuals from Wuhan. Genetic analysis confirmed the locus is in Hardy-Weinberg equilibrium, suitable for forensic applications.

Area of Science:

  • Genetics
  • Forensic Science
  • Population Genetics

Background:

  • Short tandem repeat (STR) loci are crucial markers in human identification and population genetics.
  • Understanding the genetic diversity and distribution of STR alleles is essential for forensic casework and population studies.
  • The D6S366 locus is a polymorphic marker with potential applications in forensic DNA analysis.

Purpose of the Study:

  • To characterize the allelic profile and genetic diversity of the D6S366 STR locus in a Wuhan population sample.
  • To evaluate the genetic variability and population genetics parameters of D6S366.
  • To assess the suitability of D6S366 for forensic identification purposes.

Main Methods:

  • Polymerase Chain Reaction (PCR) amplification of the D6S366 STR locus.

  • Polyacrylamide Gel (PAG) electrophoresis for allele separation and visualization.
  • Analysis of 200 unrelated individuals from Wuhan.

    • Main Results:

    • Seven distinct alleles were identified at the D6S366 locus.
    • The observed allele frequencies were consistent with Hardy-Weinberg equilibrium expectations.
    • Genetic parameters such as gene diversity (H), discrimination probability (Dp), polymorphism information content (PIC), and heterozygosity (E) were calculated.

    Conclusions:

    • The D6S366 STR locus exhibits sufficient polymorphism in the Wuhan population for forensic identification.
    • The observed genetic data supports the utility of D6S366 in population genetics and forensic DNA profiling.
    • The locus's adherence to Hardy-Weinberg equilibrium indicates random mating patterns within the studied population.
