Y-SNP - Wikipedia
WebA Y-SNP is a single-nucleotide polymorphism on the Y chromosome. Y-SNPs are often used in paternal genealogical DNA testing. SNP markers. A single nucleotide polymorphism (SNP) is a change to a single nucleotide in a DNA sequence. The relative mutation rate for an SNP is extremely low.
ISOGG 2019 Y-DNA Haplogroup Tree
WebThe Y-chromosome haplogroup is determined by performing a sequence of SNP tests. Each line lists a haplogroup or subclade in boldface, then one or more SNPs follow on the same line. For a sample to belong to a particular subclade, it must test positive for any one of the SNPs appearing on the line, providing positive results were obtained for ...
