There are a number of companies that will test and interpret your genome for you. This is about the “big three.” Average joes like myself who are tracking their genealogy (as opposed to people wanting information about family-of-origin, say, or who have DNA drawn from areas of the world less studied than Britain/Europe). I don’t pretend to know very much about the science of it, but at least at this basic level some may find it worthwhile to see the comparisons.
