Dna snp explained
WebJun 5, 2024 · The different Y-DNA haplogroups listed to the right are a function of the “Terminal SNP,” meaning the SNP that tested positive furthest out towards the tip of the branch of the tree. Four matches have had additional SNP testing which shows their terminal SNP to be either Z30754 or M217. WebSNP is a single base pair change, a point mutation, and the site is referred to as SNP locus. SNPs are the most common type of DNA polymorphism, occurring with a frequency of one in 350 base pairs, and accounting for more than 90 per cent of DNA sequence variation.
