Area of Science:

  • Forensic Genetics
  • Computational Biology
  • Statistical Genetics

Background:

  • Kinship analysis in forensic science relies on genetic evidence to establish familial relationships.
  • Calculating the strength of genetic evidence typically involves likelihood ratios, which can be complex for non-standard relationships.
  • Existing methods may not efficiently handle diverse kinship scenarios encountered in genetic identification laboratories.

Purpose of the Study:

  • To develop a computerized algorithm for deriving likelihood ratio formulas for any defined kinship problem.
  • To provide a general method for calculating the strength of genetic evidence in various familial relationship disputes.
  • To demonstrate the algorithm's utility across a range of complex kinship cases.

Main Methods:
