Ancestry

Knowing our origins and tracing our evolutionary path, both as individuals and as a species, has always been fascinating.

As we know, our origins as a species date back to the African continent 200,000 years ago. Since then, there have been many paths taken by humans across the different continents of our planet up to the present day.

The sum of all the events and demographic processes is what configures the genetic composition of the current populations, making each one present particular characteristics.

Fortunately, nowadays, thanks to the advances in genetics, the ancestry DNA test developed by tellmeGen and the new improvements we have made and incorporated in our update, you will be able to discover who your ancestors are through the exhaustive study of your genetic composition and, thus, find out even more precisely what your origins are. At tellmeGen we are always at the forefront of genetics and medicine to offer you the best service and attention in our DNA test.

What do we do in our ancestry DNA test?

To determine your ancestry, at tellmeGen we use the fraction of the data obtained in your genotyping corresponding to autosomal DNA, which contains both your paternal and maternal genetic inheritance.

Subsequently, we submit this fraction of data to a strict quality control, thus allowing us to keep and use only those genetic markers of high quality for the analysis, avoiding possible erroneous deviations in our results, because quality and accuracy are fundamental values for tellmeGen.

Once identified and refined, we establish a comparison between this portion of your variation with that of thousands of reference individuals belonging to 39 ethnic groups distributed in 7 large geographic areas or superpopulations detailed below: Europe (13), Africa (6), West Asia (3), South and Central Asia (6), East Asia (7), Oceania (2), and the Americas (2).

To generate this reference sample, our bioinformatics specialists, physicians and geneticists have used public databases of human variability known worldwide and recognized by consensus by the scientific community, such as the 1000 Genomes Project and the Human Genome Diversity Project.

In this way, by studying certain patterns in your genetic variation and comparing them with our database, we are able to infer your ancestry with a high level of accuracy in our DNA testing for ethnicity.

How does the tellmeGen DNA testing for ethnicity work?

At tellmeGen we use Admixture software to infer your ancestry from a reference database generated by our experts, containing thousands of individuals of known ethnicity. This database has been generated while maintaining rigorous quality control, selecting individuals with a pure and representative ethnic origin for each ethnic group.

The similarity between the genetic composition of each of the individuals that make up the different ethnic groups that make up the database and your genetic composition will allow us to infer statistically, and in a very precise way, what portion of your DNA comes from each of these ethnic groups.

What can you expect from the new Ancestry update?

With the new update of our ancestry study, our experts subject each person’s genetic samples to a study under strict standards and exhaustive quality filters. Thanks to this, we can offer you the most accurate results and the maximum information about your ancestry from the study of your genetic material.

Thus, what you will see in your results report will be the allocation, in percentage, that we make of your genetic composition in the different ethnic groups considered, organized by geographical location. This information will be an accurate reflection of the ethnic origin of your ancestors and, by extension, of your own origin.

Discover your Maternal Lineage NEW

A mitochondrial haplogroup is a set of variations found in human mitochondrial DNA. Haplogroups trace and describe the path taken by our maternal ancestors, from the human species’ origins in Africa to its worldwide expansion.

With tellmeGen’s haplogroup test integrated into our comprehensive genetic study, you can find out where your maternal ancestors came from and their geographic dispersion across the planet in different periods of history.

In the past, imagining where your ancestors lived and how they traveled around the world hundreds of thousands of years ago was science fiction. Now, it’s at your fingertips.

How did your ancestors travel from more than 150,000 years ago to the modern period? You can now find out and consult it on tellmeGen’s map of your maternal haplogroup migrations.

Do you share a haplogroup with famous people? There are many historical figures whose maternal haplogroups we know. In addition, many contemporary celebrities have also made their genetic test results public – find out if you share DNA with them!

Ancestry… what is next?

The determination of your ethnicity is the beta version of the applications that we are developing to give you the maximum amount of information about your ancestry from your genetic material. We will continuously improve the existing databases to include new ethnic groups from unrepresented geographical areas, which will allow us to improve the extent and accuracy of the analysis of the origin of your ancestors.

Next versions of my ancestry results will include…

  • Analysis of Neanderthal ancestry: it is known that there was inbreeding between modern humans and Neanderthals at different times in our history. We will estimate the amount of Neanderthal genetic material present at your genetic composition, derived from those inbreeding processes.
  • Y-chromosome analysis: the Y-chromosome is transmitted, exclusively, from fathers to their male children. By studying the genetic variation of the Y-chromosome, it is possible to infer paternal lineages. Paternal lineages, also called haplogroups, have a high geographic specificity and are therefore widely used in population genetics studies. Because of its special type of inheritance, similar to the transmission of surnames in many human cultures, it has been used in genealogical analyses.

The scientific team at tellmeGen continues to work to offer you the best possible information about your ancestry.
