Please talk about your DNA experience to encourage Khmers to take a test to increase the Khmer DNA pool. Ideally, we want everyone to join the DNACambodia project database, which they can do by taking a FamilyTreeDNA test (the home of the DNACambodia project), or upload for free their RAW DNA files if they are or were tested by another company. If they want to participate, but don't know what they can do best in their situation, please refer them to our advice tool.
