DNA phenotyping: A possible aid in criminal investigation

Abstract

This article examines DNA phenotyping in general and highlights international perspectives regarding the use of this technique. The article interrogates the genetic basis of predicting externally visible characteristics, the potential value of the technique, and the pitfalls regarding its use. Despite the ethical and legal concerns and debates concerning DNA phenotyping, the potential value of this technique should not be underestimated. In the context of the high number of serious crimes such as rape and murder that remain unsolved in South Africa, the responsible and scientific application of DNA phenotyping might prove to be an effective additional tool in criminal investigation.
