[Sex determination using a pulled out hair].

P Klir, J Jezková

    Soudni Lekarstvi
    |May 1, 1984
    PubMed
    Summary

    Forensic scientists can now determine biological sex from a single hair. This new method detects sex-chromatin and Y-chromosomes, even in damaged hair samples.

    Area of Science:

    • Forensic Science
    • Genetics
    • Molecular Biology

    Context:

    • Accurate sex determination is crucial in forensic investigations.
    • Traditional methods may require more biological material than available.
    • Hair analysis presents unique challenges due to sample degradation.

    Purpose:

    • To present an original preparation technology for sex determination.
    • To enable sex determination using minimal biological evidence, such as a single hair.
    • To facilitate the detection of both sex-chromatin and Y-chromosomes.

    Summary:

    • A novel preparation technique allows for sex determination from a single human hair.
    • The method is capable of detecting sex-chromatin and Y-chromosomes.
    • This technology is effective even with compromised or fragmented hair samples.

    Impact:

    • Enhances forensic capabilities for identifying individuals from trace evidence.
    • Provides a reliable method for sex determination in challenging forensic cases.
    • Expands the utility of hair analysis in criminal investigations.
