Ancestry.com To Add DNA Test Results
Spamicles writes "For less than $200 and a cheek-swiped cotton swab, you will soon be able to add DNA results to family tree Web sites. Ancestry.com plans to launch the DNA testing product by the end of summer, offering customers the possibility of finding DNA matches in the site's 24,000 genealogical databases. By taking a simple cheek-swab test and comparing results against DNA profiles in a test-results database, virtually anyone can uncover genealogical associations unimaginable just a few years ago. Users can easily connect with and discover lost or unknown relatives within a few generations, as well as gain insight into where their families originated thousands of years ago."
FFS! Rather than moderate the /dribble about DNA forensic testing as OT, I'll contribute.
This is a valuable service (yes there are others available) that tests certain parts of the mitachondrial DNA to establish your maternal lineage and tests certain parts of the Y chromosome (I make the assumption that 98% of the readers are male) to establish your paternal lineage.

Studies have generated a range of rates of "non-paternity events". There's an article with more details in this month's The Atlantic (subscription required):

From the article:
"When geneticists do large-scale studies of populations, they sometimes can't help but learn about the paternity of the research subjects. They rarely publish their findings, but the numbers are common knowledge within the genetics community. In graduate school, genetics students typically are taught that 5 to 15 percent of the men on birth certificates are not the biological fathers of their children. In other words, as many as one of every seven men who proudly carry their newborn children out of a hospital could be a cuckold."
"Non-paternity rates appear to be substantially lower in some populations. The Sorenson Molecular Genealogy Foundation, which is based in Salt Lake City, now has a genetic and genealogical database covering almost 100,000 volunteers, with an overrepresentation of people interested in genealogy. The non-paternity rate for a representative sample of its father-son pairs is less than 2 percent. But other reputed non-paternity rates are higher than the canonical numbers. One unpublished study of blood groups in a town in southeastern England indicated that 30 percent of the town's husbands could not have been the biological fathers of their children."
