My information on the DNA comes from ancestry.com. There are actually three types of testing that can be done: Paternal Ancestry Signature (Males Only) This report presents your Paternal Ancestry Signature as revealed by analyzing 24 different locations on your Y-chromosome. The fascinating aspect of a Paternal Ancestry Signature is that it does not uniquely identify you as a single individual, but uniquely identifies your paternal line. Maternal Ancestry Signature The Maternal Ancestry test analyzes your DNA and returns your genetic identity that was inherited from your maternal ancestors. This test uses Mitochondrial DNA (mtDNA) Sequencing to establish relationships. Native American Signature This test can determine if your maternal heritage is Native American. Your identity is shown by the values associated with your Mitochondrial DNA. Cost is based on which test you have done. I did the Paternal Ancestry Test (cost $196.95) as a last resort to "hurdling my brick wall". I would also like to participate in the LDS program; however, I was out of town when they were in my area several months ago. As many Barkers as there were.... I cannot figure out why some of us are not related! I am beginning to believe their motto was 'Secrecy, Secrecy, Secrecy!" Bob Barker
