SNPs and STRs

BEFORE tackling the haplogroup pages, project members new to Y DNA testing are advised to have read and digested part 3 of the DNA Tutorial (understanding STRs and intro to SNPs). Part 4 might be beneficial too (more on SNPs).

Then use the HELP page as a guide for interpreting the contents of your haplogroup page on this website.
