What is the genetic make of modern day Scottish people?

In genealogy it sounds like a stupid question, as genealogy is about researching ancestry via cited written records and has nothing to do with the genetic make up of people in Scotland or anywhere else, nor do we research about the Picts and Gaels...we have enough problems finding quality records up to 500 years ago let alone prior to that...................search online for DNA testing of Scotland where you may ( or may not) find some information about this....the BBC history websites are a good place to start
