The Cherokee Nation requires the roll number listed under your family member’s name to recognize your family’s Cherokee heritage. While genetic ancestry testing is becoming more advanced, it is still not widely accepted as a method of confirming Cherokee heritage.
Is ancestry DNA accurate?
Reading your DNA is a first step in generating your AncestryDNA results. Accuracy is very high when it comes to reading each of the hundreds of thousands of positions (or markers) in your DNA. With current technology, AncestryDNA has, on average, an accuracy rate of over 99 percent for each marker tested.

Which parent determines the blood type of the child?
Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.
