Area of Science:

  • Forensic Genetics
  • Molecular Biology
  • Population Genetics

Context:

  • Paternity determination is crucial in legal and social contexts.
  • Resolving dubious paternity cases requires reliable scientific methods.
  • Genetic analysis offers a powerful tool for accurate paternity testing.

Purpose:

  • To evaluate the utility of specific genetic markers in resolving paternity disputes.
  • To report the experience of a Colombian University in applying genetic testing for paternity cases.
  • To assess the efficacy of 14 genetic markers in paternity exclusion and attribution.

Summary:

  • A study analyzed 349 cases of uncertain paternity using 14 genetic markers (serologic and electrophoretic).
  • Paternity was excluded in 50 cases and attributed with >0.99 probability in 34 cases.
  • Probable paternity (index 19-100) was found in 85 cases, with 179 analyses being inconclusive.

Impact:

  • The selected genetic markers demonstrate utility as a first-line approach in paternity investigations.
  • This genetic testing strategy can aid in resolving complex familial and legal cases.
  • The findings support the use of genetic analysis for efficient and accurate paternity determination.
