SNPs are present to some … WebSNPs are single changes in the DNA, and lots of times they change SUPER slowly (like, over thousands of years), so they point to your paternal ancestors’ ancient populations and migrations. However, there are lots of SNPs that may have changed in more recent generations, but just haven’t been well documented yet.
