Y-DNA

Chromosome Y is a piece of nuclear DNA that is inherited only from father to son and carries male sexual characteristics and fertility. Since chromosome Y is inherited only in the paternal line, it is possible to find out the origin of the male lineage by its analysis or to find distant relatives with whom we no longer have a common surname.

If we go back to the history of each of us about 60,000 years ago, we will find one common ancestor of all living people. This ancestor is called the Y-chromosomal Adam, and was originally from Africa. All men living today have a piece of this Adam's DNA in them, but over the millennia, there have been various small changes that have been inherited and help to determine the origin of each of us along the paternal line.

Examination Principle: Chromosome Y is the smallest chromosome in the human genome and much of its DNA is the so-called non-combining non-coding region, which is a suitable "recording device" for genetic changes. In these sections, both single nucleotide polymorphisms (SNPs) and multiple short tandem repeats (STPs) are conserved. These sections are analyzed by molecular genetic methods and the result of the examination can be used to reconstruct family history.

Y-chromosome analysis can take us up to 4000-5000 years back in the family history.

For testing it is necessary to send a sample with male genetic equipment. I.e. men can send their own sample of buccal mucosal swab, women from a blood relative (father, brother, father's uncle).
