Geographic Ancestry Test
What is Geographic Ancestry?
Since its origins, Homo sapiens has been migrating across the planet, diversifying into different populations and cultures, which have interacted and intermingled with each other. Our DNA has been able to collect all this information and trace the historical trajectory of our ancestors.
The Ancestrum geographic ancestry test allows us to determine the origins of your ancestors on a geographic level. You will be able to know with which regions around the world you share ancestry signals, indicating, in a reliable way, the areas where your ancestors come from. You will get a summary of the genetic ancestry reaching you through your parents and previous ancestors.
Your ancestors 800 years back
In our analysis, with a geographic DNA test, we go back about 800 years on average, although we do not take into account the last 250-300 years, as we consider that they do not have sufficient scientific influence, as they are too recent. Therefore, it would not be strange if the information in your Geographic Ancestry report does not match what you know about your most recent ancestors (parents, grandparents, great-grandparents…).
This study is completed with our Historical Ancestry study, which covers from the Paleolithic to the Middle Ages. Between the two studies, we offer you your historical origins from up to 35,000 years ago.
700,000 genetic markers
Our methodology is based on the analysis of more than 700,000 genetic markers, which is compared with a reference panel, composed of thousands of representative samples from every geographical region today. The algorithm developed by Ancestrum locates all the genetic differences and similarities between your DNA and that of all the samples we have in our reference database and, through various advanced statistical calculations, it is able to determine, very accurately, your ancestry and genetic roots.
Nearly 2,000 regions analyzed in our geographic DNA test
We have a broad reference across the globe and in total, we have just under 2,000 regions defined by representative samples. At Ancestrum we use a unique technology that is different from other companies, which allows us to generate a more accurate report than most of our competitors.
In this geographic ancestry test, we study your autosomal DNA, which reflects a summary of the genetic information inherited from your father and mother, who in turn inherited from your ancestors over multiple generations.
While genetics is not an exact science and neither are the results of an ancestry test, the Ancestrum geographic DNA test has a high level of reliability and accuracy.
Robust methodology for reliable results
There are different methods and approaches to carry out the calculation of ancestry signals, which may yield different results. But the fact that different results can be obtained does not imply that they are incorrect. Factors such as the number of genetic markers used in the analysis, the diversity of the reference against which the markers are compared, the nature and complexity of the algorithm, and the statistics on which it is based influence these results.
At Ancestrum, we understand the importance of accurate and reliable results when it comes to tracing your geographic ancestry. Ancestrum’s algorithms incorporate a robust statistical basis which, coupled with the exhaustive representativeness of the reference sample, which ensures the genetic diversity of the human populations included, and the high density of genetic markers we include in the geographic DNA test, allow us to provide a very detailed and accurate result of where your genetic roots are most likely to come from.
