Women do not have a Y chromosome so there is no point in doing a surname test for women. Women do have mitochondrial DNA (men do too). The mitrochrondrial DNA (MtDNA) is passed down from mother to daughter through the generations. Family Tree DNA does our surname tests and they also have MtDNA tests. They can be very interesting to. If you would like more information go to http://www.familytreedna.com MtDNA can be used to determine Native American ancestry. Both males and females can test to see if their female ancestors were Native American. Let me explain a little. My name is Bette Bunker, mom Arline Mills, gma Cora Freeman, ggma Addie Palmer, gggm Elizabeth Bangle, ggggm Angeline Caswell. As you can see we do not share a surname. I have a brother and sister who share the MtDNA that I inherited from these women. My brother can trace the DNA of these women back as easily as I can. We all match. However, my brother also has Y-DNA inherited from my father that neither my sister nor I have as only males have Y-DNA. The MtDNA tests can determine which group you are descended from. There are about 12-15 distinctly different women way back in the ages from which we are all descended. The researchers can determine which of these women you descend from and also which areas these DNA types migrated into at certain times. DNA testing is fascinating and has resolved some real puzzles in the Bunker family already. You might also be interested in the MtDNA testing. While women have no Y-DNA to test, if you have a brother and it seems certain that you have the same father, you can get him tested to see which Bunker group you are in. If you have no brother, a male Bunker cousin or an uncle or grandfather will work. This is as close as a woman can come to ascertaining the group she belongs in with Y-DNA. However, there are paternity tests too where both parents and the child are tested and they can be accurate to 99.99% to determine the parents of the child. In these tests the recombinant DNA is tested as well as the MtDNA and in males the Y-DNA. Recombinant DNA is the DNA you get from both parents. It is too complicated for me to understand completely and definitely too complicated for me to try to explain but there are numerous sites on the web that you can search by just putting DNA in your search box in your browser.
