GenoGraphic Test - DNA test of genetic origin - GenoGraf

Unveil the truth about your origins

The Czech basin was populated as early as 2 million years ago. Within that time our land has seen the exchange of many various cultures, ethnicities, and nationalities.
The Celtic, Germanic, and Slavic groups are among the most historically important.

Do you want to know if you are closer to Germanic or to Slavic ancestry?

This and much more can be discovered for every human thanks to the information of molecular genetics and its applications in genealogical research. Information of one’s origin is held in each human’s genetic makeup - DNA. Thanks to molecular genetics, today it is possible to search and read these genetic “records”. It is therefore possible to look deeper into the past than can be done through registry offices, census indexes, church records, or other historic sources.

Anyone who has searched through archives and registry offices for their origin has sooner or later stumbled upon an end, where records were unclear or had been completely lost. Records in your DNA, however, speak clearly even after several thousand years. Therefore, it can be found today that the forefathers of a given concrete person lived 20 thousand years ago on a Pyrenees peninsula where they spent the winter during the last Ice Age, that they subsequently settled in western Europe in the area that is today France, and that they were a people that spoke one of the Romance languages. Another person has information in their DNA that his ancestors originate from East Africa, they migrated to the Middle east, settled in what is today Greece or Macedonia, and that, probably as tradesmen, they came from the Mediterranean to Central Europe, including Bohemia and Moravia.

How genetic genealogy works

Although genes are thoroughly mixed at each transfer from generation to generation (each person inherits one set of genes from their father and one from their mother), there is a small section in each person’s genetic information, or DNA, that changes very rarely and that, after many generations, remains unaltered. In other words, the same set or combination of genetic markers which forms the nearly unalterable part of DNA, and which you carry in your genetic information, was also carried by your great, great, great, great,………….ancestor.

In terms of the DNA of mammals, and therefore humans, there exists another segment which is inherited only along the paternal line, i.e. only from father to son. This special section is called Y chromosomal DNA or also Y-DNA, and it is here that the previously mentioned unalterable markers are found. Analysis of these markers in Y chromosomal DNA can uncover the origin and history of every person’s paternal line.

Research conducted on various nationalities and ethnicities have shown that different population types, for example Germanic people living in Scandinavia or Southern Slavs living near the Adriatic Sea, carry a set of markers in their Y–DNA that are characteristic only for them. By comparing these characteristic markers, the geographic–genetic origin can be found for a given person or group of people. In other words, whether they are genetically closer to Germanic or Slavic origin, and from which part of Europe or the world they come from.

Only males have this Y-chromosomal DNA. It is not found in females, and so the origin of the Y paternal line cannot be read. An indirect analysis of the respective female’s paternal line can be reached, however, through any of her male relatives (ideally her father, brother, uncle from her father’s side, etc.).

Besides Y chromosomal DNA, which holds the mystery of the paternal line, there also exists so called mitochondrial DNA, which, on the other hand, carries the records of origin and ancestral history along the maternal line. It is here that maternal history is hidden for a given person. Both males and females have this mitochondrial DNA. More about this type of DNA and genetic testing related to it can be found here.
