How is the test performed? You will be posted a mouthwash. Swill it round your mouth and post it back to the laboratory - it's that easy. What will the results tell me? The results will tell us how closely (or distantly) you are related to other participants in the project. By comparing the results with other people throughout the world we may also be able to tell something about the ancient origins of our family. Do I need to know anything about my family history? Yes - it is necessary to submit a 4 generation pedigree chart with the DNA sample. Don't worry if you don't have this information though - I will do the research free of charge. I'll just need you to give me a bit of background info to get me started.. Why can only men participate? The DNA tests are performed on the Y-chromosome. Women don't have Y-chromosomes. If you are female and would like to contribute to the project, then see if you can persuade your brothers, uncles, cousins, or any male relative called Tonge, to take a test. Where can I find out more information? There is more detailed information about the Tonge Family DNA Project at http://www.tongefamily.info/resources/genetics.htm .
