This section of the forum is devoted to discussions about your DNA based genealogy research. Try to keep to plain English only, remember the Terms of Use and avoid advertising.

The inherent usefulness of DNA profiling to a genealogist is obvious and depending on the type of testing can determine geographical origin, maternal or paternal origin and so on.

However it should not be seen as the be all end all, DNA tests can do some things well, but there are constraints. Testing of the Y-DNA lineage from father to son may reveal complications, due to unusual mutations, secret adoptions, and false paternity (i.e., the father in one generation is not the father in birth records). According to some genomics experts, autosomal tests may have a margin of error up to 15% and blind spots.

A very good article on the truths and myths of Genealogy DNA testing and well worth a read can be found here:
