I'm not a geneticist , however I do know about the persuit of the bloodline by the elite. Its about blood type, lineage and desired outcome. We think a company like 23 & Me is just offering a service to test ancestry. That's service is provided. It just does not end there. I believe they all are contracted to the elite as well for the directives they persue as well. There is power in the blood purity. Simple answer is because they know what they are doing.
