WebChromosome SNP Microarray A New High-density Allele-specific Diagnostic Platform pair (allele) targets that have two different forms, revealing which form is present at that locus as well as the number of copies of that DNA segment. WebA person's haplogroup can often be inferred from their STR results, but can be proven only with a Y-chromosome SNP test (Y-SNP test). A single-nucleotide polymorphism (SNP) is a change to a single nucleotide in a DNA sequence. Typical Y-DNA SNP tests test about 20,000 to 35,000 SNPs. Getting a SNP test allows a much higher resolution than STRs.
