Advantages of Single Nucleotide Polymorphism (SNP) Technique:
Useful for degraded DNA as SNP detection only requires sequencing of a short fragment
Abundance in the genome makes them invaluable in population studies and forensic casework
Higher stability and lower mutation rates compared to short tandem repeats (STRs), making them more suitable for reconstructing pedigree/lineage and in kinship analysis
Because of the ability to amplify SNPs in short fragments, SNP analysis produces better results with degraded samples where the available DNA is fragmented or old samples with low-quality DNA template
Can be used as a complementary tool to STRs, increasing available information
Can be used in individual identification, lineage or ancestry studies, and phenotypic inference
