Tracing your ancestry via DNA is becoming a popular pastime, thanks to a growing number of consumer tests available over the Internet. At least two-dozen companies sell tests ranging in price from $100 to $900, and public interest is thriving. Most of these tests, however, paint a very rough picture of an individual's ancestral origins: they're limited to the direct maternal or paternal line. But that is beginning to change.
New technologies are allowing scientists to search for markers across the genome that can more precisely predict ancestry. Much of that data is being poured into public databases, supplying much more accurate and detailed information to genetic-testing companies and new consumer tests.
