Genealogy Maps

A person who had approved his genealogy traced through DNA using the services of the company RelativeGenetics?
A map was sent to him, but does not show what percentage of that nationality is only a vague shadow grades in all geographic areas. Any advice on how to read it (chromosome Y) the map?
u can send the map. then it would be easier. otherwise look in places that tells U on the map and see what kind of sources of each place and try to identify their nationalities.
