TweetI am going to do 23 and me as it has a comprehensive health DNA screen thing. Found my fitness has an app you put in your results and it tells you if you have a propensity for heart disease, Alzheimer's ect.
It does not tell you, lineage per se. It is simply regions and %s of your DNA's origins. And lets be frank it is not 100% correct but damn close. I am adopted and have no idea of my ancestry, biological family ect.
I bet if some of my biological fam is on there and all of the sudden they see a half brother pop up on their family tree thingy they will shit themselves. Mom banged some dude and put the baby up for adoption? OH SHIT! HAHAHAHA
