That is the "type" of your ancestor. If that DNA matches another who is descended from another limb of the ancestor tree, it confirms that the DNA is correct and proves the relationship. We use a buccal swab that is obtained with the Test Kit that is sent out by the lab when you place your order. If you go to the website and click on the links to FamilyTreeDNA it will answer all questions and even show the test kit. http://small-stuff.com/HANCOCK/DNA/ Julia
