The YSTR27 test is the only genetic genealogy product on the market which offers detailed inference on the DNA ancestry of your lineage by a population geneticist. By looking at 27 different markers on your Y chromosome - a section of DNA only carried by males and inherited from father to son down the generations - we generate your Y chromosome signature. Your signature is then compared to the EthnoAncestry genetic genealogy database to understand which of a number of historical lineages you are closest to, for instance Viking, Pictish, Neolithic farmer or Cohen signatures. You will receive a pdf certificate detailing the background and procedure used to perform the tests, your individual 27 marker signature, a map of where your lineage is found today and a description of the historical lineage to which you belong. The genetic ancestry signature we provide can also be compared to others to estimate relationships and find matches. Note that this testing is not representative of your genome as a whole but rather a specific component that is highly informative for determining the ancestry of your paternal lineage.
The YSTR27 test is made up of a set of 27 microsatellite markers on the Y chromosome which identify a number of historical types, for example the Scottish Pictish type:
The Picts are believed to be the descendants of the first people to colonise Scotland after the glaciers retreated at the end of the last ice age. Until recently the degree to which present day Scots (and their diaspora) are descended from these mysterious people was unknown. However, recent genetic analysis has revealed the existence of two candidate Pictish Y chromosome signatures which are most common in Scotland, but rarely seen in England or continental Europe. EthnoAncestry is pleased to offer a test which determines your relationship to the Pictish signatures.
