Its got absolutely everything to do with physical appearance! Someone carrying R1a as his main Haplogroup is not likely to originated in West Africa! Someone carrying Haplogroup E1b1a as his main Haplogroup is not likely to be Swedish!!!!<quoted text>
Y Chromosome DNA has absolutely nothing what so ever to do with physical appearance it's simply a males paternal linage.
I was watching a Forensic Detectives about how police found a skeleton in Canada. They took DNA from the skeleton and studied the skull. It turns out the skeleton was of a East Indian woman! Scientists can tell from skeletons and hair and DNA from the hair/skeleton EXACTLY WHERE IN THE WORLD YOU ORIGINATE!!!! They can also tell what color eyes you had!
