ydnahaplogroupj2

In human genetics, Haplogroup J2 (M172) is a Y-chromosome haplogroup which is a subdivision of haplogroup J. It is further divided into two complementary clades, J2a-M410 and J2b-M12. Quite a few ancient Mediterranean and Middle Eastern civilisations flourished in territories where J2 lineages were preponderant. For instance, the Etruscans, the Minoans, the Greeks, the Phoenicians and the Romans. The Romans surely helped spread haplogroup J2 within their borders, judging from the distribution of J2 within Europe (frequency over 5%), which bears an uncanny resemblance to the borders of the Roman Empire. All the great seafaring civilisations from the middle Bronze Age to the Iron Age were dominated by J2 men.
