Abstract
Analysis of genetic profiles obtained from low template DNA samples (LT DNA) can be challenging because of increased probability of stochastic amplification artifacts occurrence. According to the recommendations of international genetic societies the quality of the LT-DNA traces results can be improved by applying low copy number (LCN) methods. Another strategy which allows to obtain better results of the analysis of LT-DNA traces is replicate the amplification of the same DNA sample and create consensus, composite (virtual pool profile) or real pool profile. The aim of the research was to analyze and compare the efficiency of modifications used in the testing of LT-DNA samples. Obtained results indicate that implementation of these methods in laboratory practice may lead to improvement in the quality of reported data from LT-DNA traces in genetic analyzes conducted to assist the justice system.
