Distribution

mt-haplogroup X is quite rare but found in populations almost all over the globe.

Overall haplogroup X accounts for about 2% of the population of Europe, the Near East and North Africa.

Sub-group X1 is much less numerous, and restricted to North and East Africa, and also the Near East.

Sub-group X2 appears to have undergone extensive population expansion and dispersal around or soon after the last glacial maximum, about 21,000 years ago. It is more strongly present in the Near East, the Caucasus, and Mediterranean Europe; and somewhat less strongly present in the rest of Europe. Particular concentrations appear in Georgia (8%), the Orkney Islands (in Scotland) (7%) and amongst the Israeli Druze community (27%). Subclades X2a and X2g are found in North America, but are not present in native Latin Americans.
