Open Access Presidential Scholars Thesis
DNA fingerprinting; Forensic genetics;
This paper consists of an overview of the procedures and criticisms involved in current forensic DNA typing. The opening presents a brief introduction to the genetic characteristics of DNA, followed by a review of the typing procedure. The main emphasis of the paper is the criticisms of the current procedure. These criticisms include an attack on the independence assumption and its justification of the use of the multiplication rule in calculating test results. A number of experts have proposed that heterogeneity within ethnic subpopulations may significantly undermine the independence assumption and render invalid the use of the multiplication rule. Others contend that any sub structuring that does occur is minor and has no practical effect on the test results. Correct application of Bayes' Theorem has been shown to seriously alter the conclusions reached in interpreting test results.
