Lee, Although my knowledge of the DNA tests is limited, and I'm sure someone else can explain this better than me, it's my understanding that a woman's DNA doesn't match her father. The tests that are done for the various surname projects are usually done for Y-DNA, which only passes from father to son. A woman can only test mitochondrial DNA, which could give her what part of the world she came from, plus, I suppose, match her with other females with the same mtDNA. The Family Tree DNA website probably has better explanations. www.familytreedna.com Jenwyl ----- Original Message ----- From: "Lee Cate" <leecate@cddn.com> To: <TNWEAKLE-L@rootsweb.com> Sent: Sunday, July 22, 2007 4:03 PM Subject: [TNWEAKLE] DNA TESTS Do we have anyone on the list who is familiar with the DNA Testing Projects for various surnames? If so, can you tell me the answer to this question? I have a friend who was adopted at birth. She has received her adoption records from the state and is searching for information about her birth parents. The adoption papers only furnish the name of the mother and her family. The father's family is listed as unknown. If the adoptee furnishes a DNA sample would it be possible to learn the surname of her birth father by comparing the results of her tests with the results of surnames already done in this project? Would this information be furnished when the test results are received? Any information will be appreciated.
