Abstract:
The study presents the results obtained by LightSNiP method with the use of 2 SNPs located on Y chromosome. The purpose of this study was examination of the mixture of the genetic material in the form of male and female blood in different dilutions. The size of available STR-PCR markers is between 100 and 500 bp, which can limit the possibility of DNA mixture analysis, where the amount of male DNA is relatively low or the genetic material is markedly degraded. Selection of appropriate SNPs placed on Y chromosome can provide information that will facilitate interpretation of the female and male DNA mixture. The test was performed on a Light Cycler 2.0, Roche Diagnostic.

Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
