How is your ancestry distributed among different populations and ethnic groups? Find out with TellmeGen
Technology has advanced significantly in recent years and genetics has not been the exception. At present, it is possible to know our origins through DNA tests. tellmeGen is one of the leading companies in this area and offers an extensive section on ethnic origins. In this article, the importance of knowing our ancestry, how the tellmeGen DNA test works and the results that can be obtained will be explored.
Our origin as a species dates back to the African continent some 200,000 years ago. Since then, human beings have traveled different paths to reach the current geographical distribution. The sum of all these demographic processes has resulted in the genetic composition of current populations, which has allowed each one to present particular characteristics. Tracing this route and learning about our origins is something that has always aroused great interest. Fortunately, thanks to the advances experienced in genetics and the new improvements that have been incorporated into the DNA test of origins developed by tellmeGen, it is possible to discover in a more precise way where our ancestors come from.
To determine a person's ancestry, tellmeGen analyzes the genetic variants that occur in the autosomal region of their DNA, commonly known as SNPs (single nucleotide polymorphisms). SNPs are a type of genetic markers that are very useful when it comes to establishing a person's ancestry, since each population has unique genetic variants.
The DNA analysis process to determine a person's ethnic origin is carried out in three phases. The first phase consists of quality control of the genetic material. Once the ancestral DNA kit is purchased and the genetic material fraction is collected, it is subjected to strict quality control. Only those genetic markers that meet the quality standards are kept for analysis. In this way, it is possible to reduce possible deviations in the calculations and generate highly accurate results.
In the second phase, a comparison is established between this portion of the person's genetic variation against a large database that includes thousands of reference individuals belonging to 53 ethnic groups spread over 7 large geographical areas: Europe, Africa, West Asia, South and Central Asia, East Asia, Oceania and America. In addition, thanks to the latest update on the ethnic origin test, it is possible to provide more detailed information about a person's ancestry, since a breakdown of the reference populations into regions has been incorporated into the DNA test of origins. more specific.
The elaboration of these reference populations is one of the key points in the process of calculating ancestry. High-quality reference populations allow greater precision when determining the genetic origins of each of the users. We can also know the percentage of Neanderthal DNA in our genetic material
Another interesting aspect that we can find out through the tellmeGen origins DNA test is the percentage of Neanderthal DNA that we carry in our genetic material. Neanderthals were a species of hominids that inhabited Europe and Asia approximately 400,000 to 40,000 years ago, interbringing with modern humans at some point in history.
Modern humans outside of Africa have on average between 1.5% and 2.1% Neanderthal DNA in their genome. This percentage varies according to the geographical region of the ancestors and can influence the physical and genetic characteristics of each person.
In addition, it is also possible to know the percentage of ancestry that we have in different populations and ethnicities. For example, we can know if we are mostly European, African, Asian or American. This can be especially interesting for those people who have doubts about their roots or who want to know more about their family history.
The tellmeGen origins DNA test is a very useful tool to discover our ancestry and learn more about our origins. It not only allows us to know our paternal and maternal haplogroup, but also the percentage of Neanderthal DNA that we carry in our genetic material and how our ancestry is distributed in different populations and ethnic groups.
In short, thanks to advances in genetics and the tellmeGen origin DNA test, we can discover more about our history and our ancestors. It is a useful and precise tool that allows us to know where we come from and what our unique genetic makeup is. If you are curious about your ancestry, don't hesitate to try the tellmeGen origins DNA test!
