O'Hara DNA Project Website - Y-DNA SNP

The major branch points on our shared paternal lineage trace back through genealogy, history, antiquity, and ancient anthropology to reach our early hominid ancestors who lived in Africa. Recent (terminal) branches may be as recent as ten generations old or several thousand years. Thus, they are an established way to trace the migrations of human populations from the earliest times to the present. The branches on the paternal tree are haplogroups. SNP markers on the Y-Chromosome define them. This page displays Y-Chromosome DNA (Y-DNA) SNP results for the project. It shows Y-DNA haplogroups and all SNP results both positive (derived) and negative (ancestral). A plus, +, sign denotes positive results. A negative, -, sign denotes negative results. You may learn more about Y-Chromosome SNPs on the Understanding Y-DNA SNP Results learning page.

Learn more about this page. This page displays project members’ Y-DNA haplogroups and SNP results. Predicted haplogroups are in red, and confirmed haplogroups are in green.
