Paternity testing 3: exclusion probabilities

Area of Science:

• Forensic Science
• Genetics
• Immunology

Background:

• Blood typing systems are widely utilized globally for paternity and non-paternity testing.
• Paternity studies commonly involve presenting conditional and unconditional exclusion probabilities.

Purpose of the Study:

• To derive explicit formulae for unconditional exclusion probabilities in paternity testing.
• To present microcomputer-suitable algorithms for calculating exclusion probabilities across diverse blood systems.

Main Methods:

• Derivation of explicit formulae for unconditional exclusion probabilities.
• Development of algorithms for calculating exclusion probabilities applicable to any blood system.

Main Results:

• Algorithms were developed for calculating paternity exclusion probabilities using microcomputers.
• These algorithms eliminate the need for system-specific formulae, accommodating new or extended blood systems.

Conclusions:

• The developed algorithms offer a generalized approach to calculating paternity exclusion probabilities.
• This facilitates efficient and adaptable paternity testing across various blood group systems.
