Genetic Genealogy

Today, standard genealogical research (in parish registers and other historical sources) is often supplemented by rapidly developing methods of DNA analysis. This trend has given rise to a modern field known as genetic genealogy. Testing autosomal DNA, the Y-chromosome (paternal line), and mitochondrial DNA (maternal line) can help genealogists find an unknown father or uncover family ties.

Errors can occur in parish registers. I am not saying they are intentional. They were written by people, and people are fallible. But as the well-known Latin proverb says: The mother is always certain, while the father is always uncertain. And even with the mother, it might not be one hundred percent true. The findings are confirmed by genetic matches. The transmission of genetic information from parents to offspring follows the basic principles of inheritance, and these cannot be fooled.

DNA analysis combined with genealogical programs opens up a truly broad field for anyone interested in exploring their roots. In addition to finding unknown relatives, researchers can also trace their ancestry back to a hypothetical Adam and Eve by mapping migration throughout human history, or discover famous ancestors with a similar genetic makeup to their own. Genetic genealogy also plays a significant role in identifying perpetrators of serious crimes in cases where other investigative methods have not yielded the desired results.

The aim of this blog is to explain the subject of DNA testing and the use of its results in the fields of genetic genealogy, paleogenetics, and population genetics to the lay public in an accessible and understandable way.
