Y-(STR), DIP-(STR), and SNP-(STR) are useful alternatives for testing the low quantity of DNA in solving the challenges in interpreting forensic genetic profiling. In an unbalanced mixed DNA, partial DNA is often not detected due to the effect of masking by the dominant DNA. Therefore, in such cases interpretation of the results is limited. Furthermore, profiling of these specimens cannot be performed using conventional forensic genetic methods. Biomarkers including Y-(STR), DIP-(STR) and SNP-(STR) perform well in detecting DNA contributes in the mixed sample. In the present research, the performance of each is evaluated separately.
