Summarize the following:
By looking at all of your DNA, it can give you a rough percentage of your ancestry by country or region. Know that there are inaccuracies in the tests. There are some things the tests cannot tell very well, because the DNA is similar between some countries. As an example, rarely can a test distinguish between English and Scottish, or Russian and Polish. These tests give results for all of your DNA, not just the male line or the female line. Many of the more modern tests will give you more information than just your ancient ancestry. The original National Geographic test is only focused on the ancient results. You will get your percent of ancestry by country or region. You will also get more "deep ancestry" information. As an example, you may get your percent Neanderthal. Or, you may find the migration patterns of your maternal or paternal lines. Enjoy learning about your ancestry.
