Question:

I bought a Genetic/DNA test for family origin purposes.?

I got back the "Y" DNA gene markers on a separate sheet, the "Mitochondrial" DNA gene markers on a separate sheet, and Map of the World with shaded areas on it. Is there an easy way to tell what the DNA markers correlate with? E.g., "Marker XYZ" is Mediterranean (or African, or Native American, etc. in origin).

The Mitochondrial test is strictly for your maternal line. The markers are matched to other people tested, and they only way that a correlation to a location is established is through accumulated knowledge of human migration. The markers are not like GPS coordinates, except that you match to other people, who happen to originate in an area.

There are many faults with DNA still. For example my biggest complaint is that you can only get 1 ancestral line, the Surname, or the Maternal line. The combination of hundreds of other contributors to your Gene pool, don't even get put into the mix.

Creating your Family Tree as accurate as possible is much more informative and gives a clear picture of where you really come from. If you do a Paternal and Maternal DNA test, you have 2 branches that you may find matches to. After 6 Generations, there are 64 contributors to your Gene pool, and you have only traced 2 with DNA. A few generations more, and it seems insignificant, with respect to contributors to who you are, and where you come from.

See the last site for a graphic example of this, it shows the paternal test but notice that only one connection to the previous generation is made. So, clearly most of your genetic content is being missed.

There are 3 people that have had DNA tests in my Family Tree, and it is helpful information for the ancestral line that they are in, it helps confirm relationships, and facts, or belief that the facts are correct. The point is that Genealogy is a balance of evidence and proof in each ancestral branch.
