Descendents of the mongols

Possibly in Iraq not south of that. I don't think the Mongols or the Turkic troops under Tamerlane managed to create any ethnic impact on the natives there. Also, the Turks in Turkey aren't mostly Turkic, they are Lydian, Hittite, etc. -- Indo-European mostly.
Mongols also invaded parts of Eastern Europe but they were never so numerous as to pass down their genes in any large quantities. in smaller quantities, nearly all of us whose ancestors come from Eurasia have some Mongol blood in us.

You are correct. The Mongols did not mix with the population of Iraq, Lebanon, Syria or Jordan.

The Mongolian blue spot is an interesting marker. It shows up bottoms of lots of little Hungarian babies who otherwise look quite European.
