There is a DNA test that women can take that can be useful for genealogy purposes, namely the Family Finder test at Family Tree DNA. It is an autosomal test that identifies strands of DNA from all your ancestors for about 5 generations back. If you have some matches that indicate a relationship, then you can compare ancestral surnames to see where it is likely you share a common ancestor. Note that the results are limited to the Family Finder database, which currently is much smaller than the yDNA database. Men can also take this test. For more on this test, see http://www.familytreedna.com/faq/answers.aspx?id=8#879 Another test that women (again, men can also take this test) can take is the mtDNA test, which tracks the mitochrondial DNA of your direct female lineage back forever. But since mitochrondial results only identify your ancient maternal "clan", they are not much help for most genealogy purposes. For more on this test, see http://www.familytreedna.com/faq/answers.aspx?id=8#507. These tests can be ordered through the Bowers DNA Project. However, since the focus of the project is yDNA, mtDNA and Family Finder results are not presented there.
