Paternity testing uses genetic markers like blood groups and DNA to establish biological relationships. DNA technology significantly enhances the accuracy of these legal and scientific determinations.

Area of Science:

  • Forensic Genetics
  • Molecular Biology
  • Immunogenetics

Context:

  • Paternity testing is crucial in legal and social contexts.
  • Traditional methods rely on Mendelian inheritance of detectable gene products.
  • Established systems include red blood cell groups, isoenzymes, serum proteins, and the Human Leukocyte Antigen (HLA) system.

Purpose:

  • To outline the laboratory methodologies employed in paternity testing.
  • To highlight the evolution of techniques from serological markers to DNA analysis.
  • To emphasize the precision and reliability of modern paternity testing.

Summary:

  • Laboratory tests for disputed paternity analyze genetically determined, dominantly inherited gene products.
  • Commonly utilized systems include red blood cell groups, isoenzymes, serum proteins, and the HLA system.
