How does the TribeCode test work?
First, you collect a small amount of saliva using the TribeCode collection and preservation kit that we send to you. When we receive your sample, the DNA is isolated, sequenced and matched to the DNA sequence in our database representing 62 different populations worldwide. Because all humans share 99.9% of the their DNA sequence, the portion of the DNA distinguishing populations is relatively small so we analyze at a very detailed level to power accurate ancestry analysis. We also analyze the entire sequence of your mitochondrial DNA (mtDNA). This DNA is passed from mothers to their children, males and females. For men, we also sequence their Y chromosome to determine paternal ancestry. We deliver your ancestry results in a fun, interactive, web- accessible report.
