[The analysis of DNA amplified fragment length polymorphism in forensic identification expertise: the possible sources of errors under nonoptimal conditions for the polymerase chain reaction].

Analyses the effects of nonoptimal conditions of polymerase chain reaction concerning the initial amount of matrix DNA and duration of its amplification on the amplification picture of hypervariable tandem-arranged locuses of human genome. Shows the causes of its possible ambiguous interpretation leading to inadequate expert conclusions in forensic gene-identification expert evaluation. Outlines the approaches to solution of this problem.
