Ten numbers that can trace your family tree
An Oxford University spin-off company is to launch a service that will enable the public to trace their ancestors by typing DNA code into the internet. The service from Oxford Ancestors, founded by Brian Sykes, professor of genetics at Oxford, can be used by anyone who knows their ten-digit code for their Y chromosome, which is easily found by sending the company a swab taken from the inside of your cheek, and £150. When the code is typed into the website, it will bring up the matches for a person's surname and DNA and the country where they live.
