Haplogroups, explained
Two small parts of your genome are inherited along a single line: the Y chromosome from father to son, and mitochondrial DNA from mother to child. Each carries a lineage label with a known geographic history. These pages give the short version for every lineage gnomancer reports, written for people who just got their result.
