I have received my DNA results and am a little bit confused as to how they should be interpreted. My results showed that I am 98% British Isles and 2% Uncertain. All my ancestors on my Tree do come from the British Isles so this is not the issue.
My confusion is due to not being able to interpret what "British Isles" really means. I know that the British Isles were a crossroads for many different cultures - including Scandinavian, among other peoples. Therefore, I would have expected some breakdown in the ethnicities shown for a person who is so strongly "British". But this is not the case for me and for many others.
My question is: Is there a real "Briton" that is genetically distinct and detectable? Or is "British Isles" simply a typical blend - kind of like a standard seasoning? (A little of this, a pinch of that?) What does it mean to be "British" and why is it not broken down into the separate ethnicities that contributed to this "Britishness"?
