13M wants to do ancestry testing, any drawbacks? I am hesitant and I don't know why

I know that they can be unreliable, and he understands the same. I also have no concerns about finding out dirty secrets, at least not on my end.Two questions:I am nervous about putting his DNA results into the public, it seems to me he can't consent to the idea of his DNA living in a database forever. Am I overreacting?If I do decide to gift him a test, what are the most reputable sites (not necessarily most famous) that we could use? via /r/Parenting https://ift.tt/2VdPRnv
