  • Summary

    The relentless advance of DNA typing capabilities leads to complications and concerns. It is one thing for someone to be able to obtain your ABO blood type from a tiny spot of blood and another thing to know your eye color and ancestry. Some of the concerns are due to misconceptions, but others can pit personal privacy against perceived security. Practices and policies have not caught up with capability. We highlight a few of these current dilemmas in this chapter.

  • Forensic DNA analysis plays a central role in the judicial system. A DNA sample can change the course of an investigation with immense consequences. Because DNA typing is recognized as the epitome of forensic science, increasing public awareness in this area is vital. Through several cases, examples and illustrations, this book explains the basic principles of forensic DNA typing, and how it integrates with law enforcement investigations and legal decisions. Written for a general readership, Understanding Forensic DNA explains both the power and the limitations of DNA analysis. This book dispels common misunderstandings regarding DNA analysis and shows how astounding match probabilities such as one-in-a-trillion are calculated, what they really mean, and why DNA alone never solves a case.
