Comment: Theory And Practice In Dna Fingerprinting, Richard O. Lempert

Throughout her useful paper on DNA identification, Professor Roeder properly attends to both theory and practice. Thus she acknowledges the theoretical soundness of certain criticisms that have been made of the standard paradigm used to evaluate DNA random match probabilities but argues that in practice these criticisms matter little. I am thinking here of the arguments that those cautioning against overweighing DNA evidence have made regarding the undeniable existence of population substructure and its potential implications for independence assumptions supporting the application of the product rule and for the use of convenience samples, such as data garnered from no more …

Forensic DNA analysis typically proceeds by first determining whether alleles (one of two or more alternative forms of a gene) found in DNA apparently left by the perpetrator of a crime at a crime scene (the "evidence sample") match alleles extracted from a sample of the suspected criminal's blood (the "suspect sample"). If alleles drawn from the two sources match, the next step is to provide information about the probative value of the match by estimating the probability that alleles extracted from the blood of some random individual would have matched the alleles in the evidence sample. Thinking in terms …
