This study examined the ability of two different SNP analysis methods to determine if they could be utilized in forensic applications and ultimately be developed into an established system for Y chromosome SNP analysis. This study examined two principle SNP analysis systems: single base extension and Pyrosequencing. Pyrosequencing was determined to be superior to single base extension, due to the wealth of information provided with sequencing and the flexibility of designing primers for analysis. Using Pyrosequencing, 50 Y chromosome loci were examined and the minimum loci required for maximum diversity for the development of a Y chromosome SNP analysis system were chosen. Thirteen loci were selected based on their ability to discriminate 60 different individuals from three different racial groups into 15 different haplogroups.
