RELIABILITY OF GENETIC INFORMATION
Dorothy Nelkin *
INTRODUCTION
The United States Supreme Court decision in Daubert v. Merrell
Dow Pharmaceuticals, Inc., I intended to replace the austere admis-
sibility standard of Frye,2 directed federal judges to assess the scien-
tific validity of the reasoning or methodology underlying expert
testimony and its relevance to the facts at issue pursuant to the Fed-
eral Rules of Evidence. Daubert is particularly interesting with re-
spect to the use of genetic information in the courtroom.3 While the
most familiar use of such information is in the field of DNA forensics,
genetic studies are increasingly cited in cases concerning family rela-
tionships and criminal responsibility.4
In this Article, I will present examples of the manner in which
genetic concepts and the findings of genetic studies are used in court.
I will then examine the reliability and relevance of this burgeoning
scientific field. The scope and influence of biological concepts are
growing, although the information brought to the courts is often
based on a weak scientific foundation, and even if reliable, may have
little bearing on the issues at stake. It is especially important to assess
the reliability and relevance of expert testimony in the area of genet-
ics, not because it is junk science as described by Peter Huber,5 but
because of its growing appeal and serious implications for legal
norms.
