Our algorithm of ancestry use only your DNA information and that of other persons with known genetic ancestry (reference populations).
Sometimes, your results may not match what you expected based on historical records or family histories. There are some reasons common reasons why this may happen:
- Some genetic populations are particularly difficult to differentiate because they share a common history. If you have genetic ancestry from one of these populations, it is possible that your DNA will map to other regions. For example, Italian ancestry may be classified as a combination of Italian and Greek / Balkan / North African.
- The more general the ancestry, the more accurate it will be.The more regional the less likely that this will be the case.
- The regions of the World and Spain are defined by the search for genetic similarity, this means, we look for where your DNA is most similar in the world and in Spain.The DNA of your family may not match where your family is from, indicating that in those countries/regions there are people who have a certain DNA similar to yours in the indicated percentage.
- Ancestry populations are defined by groups of genetically similar people, not by the political boundaries of countries.. In some cases, your ancestry may highlight differences between population history and political history. For example, if you have ancestry from northwestern France, you may be more heavily weighted toward the British Isles than northwestern Europe.
- In the case of the Native American ancestryIf you are a Native American, you may have inherited little or no DNA directly from your Native American ancestors. The further back you look in your history, the less likely it is that you inherited DNA directly from each of your ancestors. This means that you may be a direct descendant of a Native American without having any DNA evidence of that Native American ancestry.
